I'm just about at the point to try to fly out to somewhere where someone has a set just to look at them! I think from researching, either will fit a 265/295 in a 30 sidewall-- but I'm not sure about increasing additional understeer. I'd prefer a 275/295, but apparently that's a no-go without significant negative camber (which I'm not a fan of). The other consideration is the 30 series sidewall and ride height. I've read "It's terrible in comparison to the stock tires", and I've also read "It's about the same as the stock tires as the PS4S is a better tire". I don't quite know what to believe. The whole point of this is to keep a compliant ride, but to allow the car to put down the power (~550hp) from the Carbahn tune. Probably two goals at cross-purposes, and it's really starting to get to me! |

Dial in some moderate camber and even corner balance for cross weight if you have ride height adjustment available. If not just some camber and toe adjustments will dial out some understeer. AD08R and RE71R tires are very wide and stiff on the 255/275 setup so should offer improved grip. Regardless it may prove difficult to have extraordinary improvement in rear tire grip given the vast amount of power and torque being put down with any tune plus the rear wheel drive format. It's probably more reasonable to attain predictable oversteer with camber, alignment, and tire sizes in question. I did some research on tire options. 255/275 Tire Size and Specs Comparison https://f87.bimmerpost.com/forums/sh....php?t=1786104

Upon arrival of my black 763M set, my dealer removed my Cup2 tires and had a wheel paint shop pick them up for treatment. And that shop did a decent job. Dealer invoiced something close to €440 for the whole set, if my memory serves me well. Actually, I never asked whether they were powdercoated or painted. Let's keep it to "refinished". Of course, as always be careful not to scratch the wheels (rim rash). Some refrain from powdercoating wheels because of risks involved (pointing out the risk to pre-maturely age/weaken the metal alloy to the point that it is more brittle). Others point out that powdercoating curing temps are nowhere near high enough to have any effect on the metal. An alternative color for the OEM BMW wheel color 'Orbit Grey' to consider: the Ferrari wheel color 'Grigio Corsa Matte' (Ferrari Corsa Matte Grey), which is also very nice. Forum fellow Greg75 had his black 763M set for his Long Beach Blue M2 refinished in that Ferrari wheel paint color.

Talked to the Minister of War and Finance today and got cleared to pull the trigger on Apex's M2C-specific 10" EC-7's in Anthracite w/ MP4S's in 265/295-30.
Happy Christmas (and New Years, Birthday, Anniversary, etc.) to me. I even brought up the MPS suspension "down the road", and I'm still breathing, so that's a plus. |

So, I've more or less got the wheels sorted and made my decision-- right up until I got an email from Richland Forged saying that they're considering a M2C-friendly rear offset.
I thought hard about it, but the Wife still likes the Apex's better (she says that the RF's and 763M's look like stick figures, and now that she's said it, I see her point on the 30-series tires.). The Apex's are a bit cheaper and I think I'm starting to like the slightly bulkier look of the extra Y-spoke. Anyhow, the wheels/tires are on backorder until March, so now it's time to start considering/researching a suspension upgrade. The goal is a very slight ride height drop (no more than a 1/2", depending on how the Apex's look on the 30-series MP4S's), and a little better low-speed "daily-driver" comfort, but with good high-speed handling. Since I intend to "set once" and never touch things again, the MPS is kind of where I'm leaning. I have no interest in endless suspension tweaking-- I won't track the car, and I have enough other toys (Honda Element, R1200GS & V-Rod Muscle) to play with that my wife would kill me if I started disassembling yet another vehicle on a weekly basis. One other issue that I still don't quite understand is that with the Apex front wheel and the MPS, I'll need to run a 5mm spacer to clear the spring. I get that, but not how that would effect fender clearance-- you'd think I'd be solving one problem and creating another. Call me confused. So far, I'm leaning towards this setup..... - Apex 5mm front wheel spacers - Apex wheel bolts (fronts only, +5mm) - BMW M-Performance suspension - HP Autosport adjustable end-links - Milway “Street” monoballs (not sure about these for street use?) - TITEtec wheel locks - Vorshlag camber plates That's probably overkill for a street setup, but I feel that if you're going to do it, do it right. Of course, nothing will happen until I drive the car on the new wheel/tire setup for a while to see how I like it, and I'll have to see if the wheel gap drives me nuts (I considered H.A.S or lowering springs, but... too many Bad Things can happen to the stock shocks.) Comments and suggestions gladly accepted-- I'm just sort of spooling up on this. The last suspension I modified was my e46 M3 fifteen years ago, and that was more or less going to Ground Control with a credit card and saying "Here's what I want, tell me what I need". I'm trying to be a little smarter this time around. R. EDIT: I just found out that TC Kline makes a nice kit for the M2C-- single adjustable up front, double in the rear, and it includes camber plates. The front spring is also a different shape than the MPS one, so maybe I could get away without the 5mm spacers? Any comparison between the MPS and the TC Kline? R.

From what I've researched as well since I have the EC7 wheels awaiting some tires and installation, when lowered the 5mm spacer aides in clearing the inside front conical shaped spring on coils due to that wider 265 tire. With the spacer, tire being more outboard would not present rubbing issues under normal driving conditions. However rubbing can happen on the outside fender under hard compression even with stock suspension. The key is dialing in negative camber to avoid that. Personally I'm leaning towards the 255/275 35 series tires with the largest section width while maintaining a slightly stock looking stretched appearance. Another thing to consider are the road surfaces you drive on in relationship to tire aspect ratio. I'm weary of driving 30 series tires as the ride quality will suffer, will bring more cabin noise depending on the tire, increase risk of pinched flats, and possibly tram line more on highway speeds. I'm sure tire choice may impact these concerns as well. I'm also going to be on coilovers and have Vorschlag camber plates in hand waiting for install. Please report back where you land up on your selection of tires and such. It will be good to hear your experience with your selections. I'm in no rush to move away from stock setup at the moment as I want to drive the car at 1-2 HPDE events in stock form to judge for myself where I need what I need.

These wheels look beautiful on LBB - makes me want a set myself. Do you know if there's much more clearance between the caliper and barrel on these 763Ms, compared to the 788s? I just noticed a stripe from a rock getting lodged between caliper/barrel on my front passenger wheel

So. Euro bumper painted and installed. Now, it's going to cure until Feb 23, then will go in for PPF and ceramic coating.
Made an appointment for Feb 25th to go up to "the" BMW shop in Denver-- we're going to put the car on the lift and measure distances to ensure clearance with the TC Kline suspension, Apex wheels and 265/295 PS4S's-- just so that if I need spacers, I can source them when the wheels come in. Exhaust is on back-order until at least late February/early March. Wheels are on backorder until late March/early April-- so I'm thinking I'll get the suspension (and hopefully the exhaust) done in early March-- that'll give the suspension some time to settle before I bring it back up to do a solid alignment with the new wheel/tire package in April.

Just a small update:
New Anthracite Apex EC-7 wheels are on and they look great. Dinan exhaust cancelled. Another set of EC-7's on order for track duty. TCK suspension is going to be replaced with the M Performance suspension and Millway Street camber plates in late July. There were just too many issues with the TCK suspension-- changing springs would most likely have sorted things out but I didn't want to pay the ride price penalty. Here's the latest "List": Interior: - BMW 2-Series hood insulation pad & clips - BMW 2-Series left & right door seals - BMW Euro-spec sun visors - BMW luggage compartment mat - BMW M-Performance carbon fiber brake lever w/ IND orange-stitched boot - BMW M-Performance carbon fiber shift knob w/ IND orange-stitched boot - BMW M-Performance carbon fiber steering wheel trim - BMW M-Performance front & rear floor mats - Trunknets trunk cargo net - Uxcell USB Type-A anti-dust plugs Exterior: - Automotive Passion carbon fiber front & rear arch guards - BMS (replica) slash-cut 95mm black chrome exhaust tips - BMW Euro-spec aspheric side mirrors - BMW Euro-spec front bumper - Cosmoline RP-342 rust preventative spray around wheel hub bolts - Denver Auto Shield “Driver’s Package” paint protection film - Denver Auto Shield “Level 2” paint correction & ceramic coating - Door jamb paint protection film - IND matte slatted rear reflector inserts - IND color-matched M2 side markers - Radiation symbol valve stem caps - Rust-Oleum High Heat primer & paint on underside of exhaust Mechanical/Performance: - Apex Anthracite EC-7 wheels - AutoSolutions Ultra shifter - BMW charcoal air filter insert delete x2 - BMW M3/M4 intake snorkels, ducting & grills - Carbahn Autoworks Stage I software flash tune - Goodridge stainless braided brake lines - Michelin Pilot Sport 4S 255/35/19 & 275/35/39 tires - Mishimoto baffled oil catch can - Mishimoto heat exchanger w/ stone guard - VTT crank bolt capture kit Audio/Electrical/Coding: - BimmerCode App - Start-up warning, camera warning & ASD disabled, rear view camera zoom, full text messages, video in motion, shut off iDrive when door opened, convenient closing w/ remote control, door handle lights when Reverse selected enabled Miscellaneous: - BMS 17mm wheel-saver socket - BMW M-Performance indoor car cover - CTEK MXS 5.0 battery charger & maintainer - TMS Motorsports jack pad adapters - Veepeak OBDCheck BLE+ Bluetooth 4.0 OBD2 Scanner To Order: - Carbonio or Sto-N-Sho front license plate frame - CG Precision VSC-2 Variable Sound Controller - CTEK connector (Under-hood mounts) On Order: - Michelin Pilot Sport Cup 2 255/35/19 & 275/35/39 tires (for track use) - BMW M-Performance 2-way coilover suspension - Millway Street camber plates Sitting In The Garage Waiting On Installation: - BMW 2-Series left & right aluminum rear side covers & clips - BMW 2-Series left & right rear wheel housing insulation & clips - BMW 2-Series left & right trunk insulation & clips - IND silver ignition bezel - Rennline BMW M2 ExactFit Magnetic Phone Mount - Acexxon universal front lip protector - IND color-matched driver’s side door lock cover - ML Performance charge cooler cover - Turner Motorsport oil cooler skid plate - UCP clutch pedal - BavSound Ghost V2 underseat subwoofers - BavSound Revenant Pro amplifier - BavSound sound deadening packs (2) - BavSound HK S674A Stage One speaker upgrade - Boodlied 20W LED backup bulbs - TechnicPNP ASD bypass cable Further Research Required: - CarBahn Autoworks S55 keyed crank hub kit - Full-screen CarPlay - Mishimoto oil catch can petcock drain - Paul Johnson tune (w/ BM3) - Radar detector, blend mount & mirrortap (360C, R7, V1G2 or Theia) - Street/Track pads (Ferodo DS2500/Porterfield R4-S) - Thor differential/MDM flasher
