My initial test drive went well with what I think (don't know for sure) was very slight contact with the coilovers and only very minor rubbing with inner well at full turn (won't happen on track).

Thus the question if I need a 5mm spacer up front? I'm thinking I might order a pair of 5 mm spacers just in case I need them.

Anyone else running this setup?
If the tires are coming in contact with the suspension at all, you need spacers. You want a minimum of 3mm clearance between the suspension and tires (according to Apex)

Thumbs up

Many thanks for the inputs. I’m going to try 5mm spacers and see how it goes. Agree with the sentiment that no contact is best. I knew the 275 NT01s would push the limit.

Agreed. My next tire is the RS4. Still learning

Where is the rubbing occurring? On the spring, height adjuster collars, or somewhere else on the shock body?

I have tried many setups including the RE71 265/18 square. I find that anything bigger, which includes BFG R1s in 265, require a front spacer of 5-10mm. The Turner spacers are a hub centric work of art. I swap between the 7.5/10 on front and barely clear. Some of these other posts confuse me since I cant properly fit some 275s up front ( R7) let alone anything bigger, without rubbing during high compression and curbs, unless I want to raise my car back up to standard height.

I ran 5 mm spacers up front last weekend without any issues at all.

That said, the 275 NT01s are consistently 1.5-2 seconds/lap slower at MSR Houston than my RE-71 265 square setup. Most at the track, independent of car, agreed that RE-71s are categorically faster. The contributing factor seems to be the difference in sidewall stiffness between the NT01s and RE-71s. The NT01 isn't as stiff as the RE-71 and, as a result, turn-in isn't as crisp and requires slower entry and cornering speeds. The upside is that the NT01s last much longer.

I'm leaning towards taking my FL-5 18" square setup to a staggered setup. I believe the rear FL-5 is 10.5" wide. Is anyone running a staggered RE-71 setup? If so, what size in the rear?

I have an 18" square set-up on FL-5 (9.5") wheels with 255/35/18 Dunlop Dirreza tires. After my first track day I plan on switching back to staggered set-up to see the difference. Don' t know if I will get 2 FL-5 wheels for rear in 10.5 width or maybe put a 275 on the 9.5 current wheels.

The problem is one brand of 275 is not the same fit as all others. Good call on the RE-71 at 265 square...tires fit well, great grip and a little less rotational weight.

I have a staggered RE-71R setup. Pretty conservative at 255/18 front and 275/18 rear. Fitment was fine on OEM suspension settings. I've recently added camber plates and I'm running at VIR this coming weekend.

Was wondering if you went with the staggered set-up for your FL-5's. I just tracked my FL-5 Square Set-up today (9.5), and was not too impressed with it. Thinking of going back to Staggered with a 10.5" in the rear.

Tell us more...I hope to use my square set up for the first time in about 6 weeks and would like to know what you don't like about it. Thanks in advance!

Square set-up

For me running all stock, you are limited to 255's Square. This car needs more traction in the rear than that. I will keep my 255's for the front and get a pair of FL-5's in 10.5" for the rear to put 275's, or 285's, which will give me the ability to go between square and staggered. If you have camber plates or modified suspension then you have the ability to run wider tires for a square set-up. My Square set-up was still a big improvement over my stock wheels (Contis). It's just that coming out of corners and putting down power , the rear loses traction too easily so you have to feather the gas or start to slide with 255's. Enjoy your upcoming track day, it;s all good.

295s were Trofeo’s. 305s are 71Rs. The 71Rs are stickier, but the Trofeo’s have much better road manners.

Not yet - but will go that direction after I get through these NT-01s if I can find RE-71s befitting of the 10.5 wheel.

My first set of RE-71Rs ran 2 days in the wet, then 5 mostly dry track days.... And they’re pretty much done. Might be able to flip them on the rims and get a few more sessions. Probably not a full DE though. Had R-S4s mounted today. Will drive them in just over a week at Watkins Glen. Hoping they’ll have a little longer lifespan.

I ran with Hankook RS4s last season, 5 HPDE events and loved them. With the current wear I bet I get another 5 track days out of them.

Square setup with front camber plates, getting nice even wear.

RS4 will last 2X longer than 71R's. 71R's are faster and better in the cold/wet. RS4's tolerate a lot of heat and wear like iron.

I just ran my new square set up at the track this past weekend - square 265/35/18 RE71R’s on Apex 9.5in ET35 rims... wow, grip was incredible!

No idea how long they’ll last me but right now I’m just enjoying the explosion of grip over my old stock setup.

Its just amazing how they grip for the kind of tire they are and the price !

Its knowned fact these are kind of 100tw tires desguised in a 200tw shell but eventrough they are still impressive !
