How do you find the Trofeo R's drop off due to heat cycling?
I know the PSC2 drops off *really* quick from its peak grip, so even though it wears well it is certainly not an endurance type tire I don't really have a clue about car setup. I'm sure we'll be in touch once I do the install The build you have is very similar to what I'm doing with the secondary track car, the E92 6MT. It's supposed to be used on the street so it is not as extreme. I just wish I had read your suspension review, I would have gone with the Bilsteins instead of the JRZ |

I can assure you my setup is not extreme at all. In fact, my buddies are shocked at how good the car is. It is TOTALLY daily driveable. The solid subframe bushings and purple diff bushings don't change anything. Everything else I've done is just little track stuff that doesn't change any street-ability. The stock seats, make it super comfy on street, and the JRZ shocks will ride fine on the street, they can get turned way down to soft, don't worry. In terms of setup, this is very basic, but for double adjustable, it works. I use another one that is more detailed, and it just takes guessing game out, and I find you can tune the car quickly. Bilstein Trouble Shooting the Car at the Track If your car is: Loose (Oversteer) from 0° to 90° (Corner entry) • Increase compression rate on front. • Decrease rebound rate on rear Tight (Understeer) from 0° to 90° • Decrease compression rate on front • Increase rebound rate on rear Loose (Oversteer) from 90° to 0° (Corner exit) • Decrease rebound rate on front. • Decrease compression rate on rear. Tight (Understeer) from 90° to 0° • Increase rebound rate on front. • Increase compression rate on rear. When analyzing corner entry, or deceleration handling, realize that the chassis is affected by: Compression rate in front. Rebound rate at rear. When analyzing corner exit, or acceleration handling, realize that the chassis is affected by: Rebound rate in front. Compression rate at rear.

FYI- Autozone carries the entire Bilstein range, and has a 20% off coupon online. Somehow it worked, and I got a set for $29XX.xx before tax Only downside is the JRZ's on my car are basically new lol. Just too good of a deal.

Thank you for that great rundown Mvez
So, I've installed the MCS and JRZ and already have a track weekend with both MCS: 2WNR, 700/1000 springs JRZ: RS (2WNR), 500/800 springs My mind was blown at how compliant the MCS are. It's incredible. On the highway, it's essentially the same as the EDC suspension. If you don't bring down the settings for highway use from what you have at the track, it's still not worse than EDC on Sport. Very impressed. On the street there's some noise, likely because I didn't adjust the adjustable sway bar links to the right height. Dammit. I'll have to get back to that later. As suspension adjustment isn't my thing, I'm going to sell the JRZs after one track weekend and buying another set of MCS. Having two identical cars with identical suspensions is advantageous for suspension tuning! A couple questions about the CS: The rears don't seem to be height adjustable? Can you fit a 10.5 in the front?

My plan now was to move my MCS 2WNR to my secondary track car and sell the JRZs. The primary car would get MCS 3WR. For this ridiculous price, I'll just keep the MCS 2WNR on the primary car and get the Clubsports for the secondary car. The E92 which is my secondary car has a build that's almost identical to Mvez's. PFC Z54 front bbk, quickfits on stock seats, some sticky tires and it bruised a LOT of egos last weekend at WGI. I like to drive the E92 on the street so the Clubsports make a lot of sense! |

The Autozone price before the discount is the best I've seen by several hundred dollars. I'm in love with how my E36 rides on the street, so I'm hoping for the same. And yeah, the price is awesome. I wish I could have used a coupon when I bought JRZs and Motons last time lol

Hm very tempted. Moved from KW CS as it felt... underwhelming. And especially at that autozone price
The rears are height adjustable; the aluminum height adjusters are see in his second post They're threaded. 570/800 is very similar to the CS; I think anyone looking for a more track oriented set up should be wary. Not to take away from this review and the positive things about them but it IS a clubsport setup afterall and looks to be more towards a balanced approach of street AND track since the rear springs are NOT linear; they're progressive. Thanks again for the review; like many others looking at clubsport varients we bypass Bilstein since it doesn't seem readily available, but it is , and the PSS10 and 16s aren't dual-duty enough. |

Holy Crap that is an insane deal from Autozone.
I've had more track days to fine tune the setup, and I firmly stand by my initial thoughts. This is an outstanding monotube setup, built like a tank. The performance keeps getting better as I dial it in, and I moved to a 265 square setup. I have found that with a 265 square, the car is very neutral with rear bar on full stiff, front on hole 2 or 3....depending on the track. I can provide some damper settings if people are interested. One click, makes a very noticeable difference, which is great for quick setup. For reference, I was able to turn laps in the 1:15.XX range at Putnam park on 265 Trofeo-R with 10+ heat cycles already on them. For a full interior 3500lb, stock powered car, that is not shabby for warm summer weather. I think the car will get into the 14's with cool weather and a bit more sorting. It's quick at NCM too. This is some slow mid-session hooning around with my buddy chasing me in a Camaro SS 1LE, which we already know is VERY fast. This was before I put a square tire setup, the car is definitely faster now, much better in the brake zones. As you can see the car is very composed. I could not be any happier with this build.

People tend to either forget, or simply ignore that KW's are twin tubes, which is why they feel like they do. BMW uses them in cars like the GTS because they are cheaper and offer better street manners. Plain and simple. IDK what anybody says, a KWCS is simply not in the same league as a Bilstein CS. Ask any competent shock tuner, and you'll hear the same thing as a majority. The rear spring actually is linear, it just has a "progressive" section on one end that fully compresses when the car is on the ground. It's simply a built in "helper" spring. The spring also has a small angled section to help with articulation as the control arm moves through it's range of motion. This is really nice, as it helps prevent coil binding, since there aren't any articulating spring perches, which I used to use on my E6 M3 track car. This is a very well thought out piece of engineering you don't get with most other company's "kits". Also, it doesn't make any noise. This is the same linear-and-helper spring type as used OE on the 997.1 GT3/RS, which I previously owned. It works very well actually, for when on streets or bumpy tracks. If you want another spring or rate, just install it. That's easy. What's important is that the dampers are valved to handle these and considerable higher rates. I've validated that with the Bilstein motorsport directly. I have found that with an adjustable rear sway, I don't need to increase the rear rate for my current use and setup. This also helps to keep road manners in check. Not trying to persuade anybody, just passing on what I know or learned.

Everything I see about the Bilsteins gives me a warm fuzzy feeling. I've used Bilsteins in 4 cars so far and they were always top notch.
As you keep mentioning Mvez, the fact this is an oem-style kit should not be ignored. It is a key component. I've installed two coilovers and it's instantly apparent they are a kit, made by different companies and kept together with masking tape. That is a far cry from an oem setup By the way, do these have camber plates? |

There is no rubber, so it's a race-type camber plate, but camber adjustment only. My caster numbers are still fine, so there is no issue there. You can get over 3 degrees with them. I have a pretty conservative ride height, and with camber plates max'd out, I am at -3.1. So definitely room for more camber if you drop the nose further, or grind shock tower holes in a bit.
However, even with sticky Trofeo rubber, -3-ish seems just about right both in terms of tire wear and pyrometer testing. Geometry on the E9X has definitely improved over E46....

Mvez very cool info on the built-in helper spring theory. Not shitting on you or what Bilstein says by calling it a "theory"; obviously good enough for 997 gt3/rs, but curious as to why not actual helper spring set up. But very cool to know it's a linear rear in that sense.
Yes; I forgone that thought on the KWCS after purchasing; the twin tube is definitely not track oriented and definitely leaves it far behind when talking about upper echelon suspension groups. As for spring rate, would you happen to know what the range is? 570/800 to jump to a more track rate like 700/1000 I'd only assume you'd have to revalve and adjust. |

No revalving is needed for higher spring rates such as 700-1000. All performance, adjustable shocks have valving ranges which will handle 20%-30% more spring rate without any issues. That is the same for MCS, JRZ, KW, Bilstein, etc. etc. They will all tell you the same thing. You want to use 700-1000, no problem. Slap them on.

A single spring with a built in helper eliminates the helper spring and the helper spring perch, so two pieces which disappear vs a standard kit. This is great. The less pieces you have the better. KISS mentality FTW |
