What do you guys think about putting in a reputable Coilover kit like Ohlins R&T in our cars (without considering any potential warranty concerns)? Would that be a bad idea or detract from the performance?
Seems like there are some very smart members here when it comes to our cars. Glad to know we have some heavy hitters to help us get things done correctly!

I really liked the MP-HAS on my CS. It is not easy to compare spring rates because the MP-HAS have progressive rates while the stock spring have linear rates, but the consensus is that their rates are similar to the Comp pack spring rates at the static load point. I found the CS damping to be perfectly suited for the MP-HAS. For sure, the combo was not as stout as an all out "coil over" on track, but I found it struck a nice balance between street and track driving, which was exactly my use case. I liked the fact that I still had the 3 EDC modes at my disposal, perfect for a dual use car. It has to be said that there was some annoying level of NVH with my MP-HAS that were paired with GC camber plate. Nothing major, but some muted clunks when driving at low speeds over small sharp bumps. It is important to get the front-to-rear ride height well balance to optimize the handling balance. I had originally set the front too low relative to the rear, which was suboptimal to put the power down on corner exit. Raising the front a tad resolved the issue.
