and i agree with you, good suspension setups are way better performance and comfort on the street.

I installed a JRZ RS1 setup on my wife's street-driven e92 M3 and she absolutely loves it. She also finds it to ride better with 400/700 lbf/in spring rates than the stock EDC suspension.

dont let my wife see this post because she will ask for it too. i bought track wheels for her 135i before i bought my e90 and when i decided i was goig to sell them off after getting my car she was upset. she wanted the wheels and suspension too

suspension money for her car = more money for mine

I just installed a TC Kline SA set up on my M3. So far so good and the ride is great. I only track 4-6 days year now, so I got street biased spring rates, which are still pretty stiff, but much better than my previous Eibach springs, stiffer front sway bar and turner stage 2 camber plates. To be honest, I think I was hitting the bump stops a lot. I haven't tracked the set up yet, but you can already feel the difference in cornering.

The kits are on sale, about $900 off MSRP at ~$2200. I busted an EDC shock up front and the cost of replacing a pair made it worthwhile to change the whole kit at that price.

I've rode in quite a few cars with KW coilovers varying from the CS, V3, and the competition setup. They all have rode VERY hard. You hit a bump and it jars yours spine. I had back pain getting out of a KW CS E92 M3...with stock seats...going over a bump on Texas World Speedway. Its about 1/10th as bad in my car with a TCK coilover.

The trick to a comfy suspension is a quality damper setup for the car with a set of properly matched springs and properly adjusted settings.

Good day

Not sure if you've considered Ohlins R&T...seems to be well received within the M3 community. I'm really impressed with my decision.

Cheers

Thanks for any info provided.

Ohlins R&T spring rates (F/R ~345/685 lbf/in) are too soft for the track. Ohlins recommends against using higher rates without having the dampers revalved. Also, R&T dampers need to be rebuilt (with supplied spring rates) at 20-25k miles (I'm running them on my R56 Cooper S and they're worn out at ~10k street miles ).

I have not had that experience with mine and in fact I have given many locals test rides in the car and they have said the opposite - stating it feels like OEM ZCP on the street. One of my buddies thought that his Ohlins R&T ride was harsher.

That being said, I have the Clubsport 3-ways (regular club sports are 2-way), adjusted to soft-ish street settings, reasonable ride height, and I run 18" wheels, all of which are certainly contributing factors. It would change things drastically if I had the suspension settings cranked up to full stiff and / or the ride height super low, with a set of 19's.
