Not 788 but just picked it up from alignment after installing Ohlins last weekend.

I'm also on Ohlins R&T at recommended drop. Forgive the green tint to the picture - the original was too dark and I attempted some correction.

Looks nice man, hope you got everything sorted out with the sound you were getting with R&T.

All set now. Did a few miles yesterday and will be doing some back road driving this morning. No more noises so far!

Looks jacked up in the rear. Your rake seems off.

Maybe it's the angle the picture was taken but that looks way more than the 10-15 mm drop. Likely 20-25 mm in the front and 25-30 mm drop in the rear.

That looks lower than mine. Aren't you scraping like crazy?

The tire-fender gap in my relatively flat garage is about 20 mm front / 1 mm back at the moment. I did not measure before install but I do recall multi-finger gaps front and back. What is the gap on stock suspension?

Not all all, at least so far. Went back road driving today and my only gripe is it was too stiffly set for street making it unsettled at speed over uneven pavement. Easily adjusted of course.

I'm at 59cm front and 60cm back. What is yours measuring out at?

I find swells in the road when going up hill that cause the car to bounce will scrape the brake mudflap thing on rebound.

Wheel bottom to fender front is 595mm, rear 624mm. Where were you measuring from/to? Tires at set to 32psi cold. Rear wheels are 20" and front 19".

Can't give you an exact measurement of the gap but it looks a bit too much on the stock suspension.

This is how BMW measures the suspension height (and lowering):



On the stock suspension that measurement is supposed to be 620 mm all around. (on my car it was 620 mm on all corners except the front passenger where it was 622 mm)

On MP coilovers it's supposed to be 595 mm in the front and 600 mm in rear when just installed (full tank). Effectively, it's all the way down (or almost) for the rear while there's still plenty of adjustment for the front. I suppose it may settle a bit after that and may be more even eventually.

Ok, back from the garage with the official BMW measurement.

Back = 23 1/8" or 58.7 cm
Front = 23 5/8" or 60.0 cm

I appear to have a little bit of a trophy truck rake.

Did you measure from center of the wheel?
Nvmd: just saw the post above.

Important to mention that my rear ride height will seem off because of 20" rear wheel. After subtracting 2.54cm/25.4mm, I am right there at recommended level for M Perf coilovers.

That's about the same as me. I guess it just looked lower. Thanks.

20" in the rear. Guess you went w/the M3/M4 fitment and those are orbit gray?

BTW, love the car color

Thanks! Yes, M4CS fitment: 255/35 19 front and 285/30 20 rear which is why the rear height seems different. They are Orbit Gray. Alpine white looks great with the wheels and carbon fiber.
