The IPD Plenum helps a bit in the midrange from what we have seen, and a bit up top.

Now that this thread has been brought back to life, I will amend my comments. We had a couple of failures of KW clubsports with no warranty support as "it is a race part" despite the street level spring rates they use to get TUV certification. So, I will group them with the other "shelf" products like Bilstien and H&R, Ohlins etc.

Very pleased with MCS and their support on race vehicle and street driven vehicles. We supply all the required data and can custom spec spring rates. They build the shocks based on the data provided and that give an amazing range of adjustment and the ability to still fine tune spring rates. Ya, it costs a few bucks more but you are getting true motorsport level products, will incredible support. Normal lead time for use on a set of dampeners is less than 2 weeks.

If you ever need a rebuild, turn around time is super quick. Bilstein won't even rebuild your PSS9/10, and won't sell you a pair (axle set) only a full kit which they likely don't have in stock and could be months out....

For street and performance/DE MCS 1WNR is likely all most people need. In the race cars we have used 2WNR and on when spec'd 2WR systems. Our street/performance GTT uses MCS IWNR after we threw out the KW Clubsports that failed, our Cayman S used MCS IWNR and our Boxster Race Car uses MCS 2WNR.

Let me know if we can help with a MCS Set Up for you.
