Same old story with Dinan. Very high cost for not too much gain.

Same old story in response--a failure to acknowledge that the bottom line price number is one that very very few people pay, and that the vast majority of the performance gains can be had at a much lower price.

Some who live in California find value in the somewhat conservative engineering for longevity, California Air Resources Board (CARB) compliant efforts, and the equivalent warranty. Burger Tuning does not sell/support JB4 in California.

Littleoldman, is that you?

Does anyone else have this set up? Sounds fantastic. If budget was an issue (say $5-7K), what is the best way to boost performance?

I guess it depends on what you mean by performance for a street/track car. Straight line acceleration and speed? Get a bigger turbo, cool it, and get a tune.

Getting around a track? Get coilovers and camber plates. Invest in track tires, light-weight wheels, and pads.

Both? Get a bigger turbo, cool it, get a tune, get coilovers, camber plates, pads, wheels and maybe brakes. Loose some weight -- seats come to mind after the wheels.

I think you can do a pretty good job of straight-line or track for 5-7K and you'll get lots of suggestions. But both would be rough. As the car gets faster, the components to make it turn and stop get outmatched. And BMWs have always been about balance and turning. So the trick is to keep those while getting more straight-line, IMHO. And that's $.

There is a great thread by someone building/modding a M2 for One Lap. You might want to check that out. Can't find the link right now but do a search or just wait and someone will post it. You can also search threads for suggestions on turbos, inter-coolers, etc.

Thanks - I was thinking road vs track...but I get you regarding Balance - that is the name of the game for any car. You dont want high speed if your brakes dont stand up and your suspension is unbalanced.

I read a review and my take away was "upgrade the brakes".
As an ex track junkie I always enjoyed late braking (beating others deeper into the corner).

Seems that is all this would need. Late solid stable no fade braking!

Still looking for instrumented numbers for comparison

7K for nearly 100hp under warranty? Is something wrong with you?

Take it a step further and forgo the intake and exhaust and you're down to under $5k. Those 2 components claim 14 bhp. The sound produced from them is incredible though.

Yeah. But once you have 460hp for a suspension that was designed for 360hp you have to address that too. That is if you want to turn the car. Not saying that you need every Dinan bit, but it would be good to balance the power and suspension mods.

I'd have to disagree on that point considering we have a lot of M3/4 suspension components and those cars make stock what a Dinan M2 makes. And there really isn't a need for solid and adjustable bushings anyways unless you are making a serious track toy.

Something tells me that BMW engineered this car such that its suspension can handle the Dinan kit just fine. For a serious track machine, coilovers, bushings, links, big brakes, etc. make sense. But for a DD that sees a track a few times/year, there is no need for any of that stuff. Maybe some good track pads, DOT 4 and things at that level...

I've driven the 460 HP (+25 or so with DP) at 8/10s. The chassis, suspension, and brakes are more than capable and I'm not a pro driver by any stretch of the imagination. As already stated, the components are directly from the M4 which makes, at least according to Dinan, 484 HP.

My guess is that suspension improvements will make the car go faster than a bigger turbo in anything but a straight line. And if I want to go fast in a straight line there are lots of better choices than an M2. I also, suspect that BMW does not build and tune its M2 suspension to operate the 360hp car at 460 hp. The days of massive componentry overbuild are long over. You can look all over the M2 and see where they are saving nickles and dimes as all car companies do. And modern CAD/CAM technology is there to make sure you don't massively overbuild which increases costs. Weight and emissions standards are driving design decisions.

But I'm not a hater. The hp improvement for the price under warranty isn't cheap but isn't unreasonable and it meets CARB. And you surely go faster 0-60. To each his own. There are whole sections of the site devoted to very expensive cosmetic changes, too. We all value the M2 and modifying the M2 for different reasons. We're all crazy in our own way and that's a good thing.

As has been pointed out, the M2s suspension components, stock, are taken straight from the M3/M4. If they are good enough for M3/M4 power, then the Dinan kit's power on the M2 should cause them no problem whatsoever.

In another month or two, I am sure some of us will report.

The suspension is a bit of a mishmass from other models including the M3/4. And the front and rear weren't beefed up symmetrically. http://www.bimmerfile.com/2016/02/22...ng-the-bmw-m2/ The whole point was to increase stiffness for the 360hp engine. My guess is that is adding more torque and hp to a stiffer setup isn't optimal on wear and the hp would generally be lost as the suspension would create a speed bottleneck is turns (but not in a straight line.). I have no doubt off a red light, merging onto a highway, or passing on a highway the bigger turbo would show significant improvement.

Seems you like to be pushed back in your seat while I like to be pushed sideways.

I look forward to the reports.
