M3 GTS Suspension
While doing my research on my next coilover setup I discovered this.
"KW equips BMW M3 GTS BMW strengthens its M3 and broaden its portfolio with a BMW M3 GTS. The 450 horsepower strong BMW M3 GTS, made for the usage on the road and the race track, will be optimized for the usage on the race track regarding the drive system and suspension technology and will be produced individually only per orders. M-GmbH focused only on KW suspensions, that means, that all GTS-models will be delivered with a KW Clubsport suspension kit in series with separately adjustable compression and rebound damping." http://www.kw-suspensions.eu/int/kw_history.php After reading through many posts, I though Sachs was the supplier even though the GTS suspension is identical to the KW CS. Now I am a bit happier I ordered the KW CS kit. http://www.m3post.com/forums/showthread.php?t=385970 Looks like RLDZHAO had it right back in 2010

I have kw clubsport, albeit and another platform ( s/C Z4m) and they are phenomenal, they car performs on track sooooo well, the only issue i have is they are ROCK solid.... imo not very DDable..... they would drive you nuts.... again could be different on the m3s...... On the track or sprint circuits, warm sticky tyres, they are faultless, definitely one of my fave purchases, i really enjoyed bolting it all together as well, everything fit like oem parts, the quality is first rate, they do not make the slightest creak, which is nice!!!
when Bmw stick them on their GTS model that 100k plus over here in the UK..... you know its a solid setup!!!

I believe the GTS has the KW Competition 2-way adjustable line.

From the information I can gather from various sources, GTS has a mix of parts between Clubsport, Competition, and BMW's custom design.
If you want better performance, Clubsport hands down.

Thanks Richard. What are your thoughts on the CS vs. the Competition. Is it more than twice the performance difference given the price difference? Obviously, it'll depend on the level of the driver in order to tell the difference, but where you ever able to drive on a CS car vs. your Competition equiped car? .

Typically, for my customers who use the car daily and goes to the track a handful of times a year, I would recommend KW Clubsport. It offers improved performance vs. stock, a very decent ride, and design features that can handle the elements from daily driving such as snow and salt. For example, the Clubsport camber plate has a rubber boot to keep the main bearing clean, lubricated and protected from salt and debris. The front adjustable spring perches are made using steel sandwiched in between self-lubricating composites which eliminates corrosion and prevents the spring perches from seizing onto the front strut. KW Competition, on the other hand, is designed with performance and precision first and foremost. All the rubber bushings and mounts found on the Clubsport are replaced with race quality metal bearings. Springs and valving are substantially uprated based on your driving style and tire use. The camber plate is beefed up to handle increased loads from racing conditions. Also available now (just released) is an inverted front strut, increasing the strength and rigidity of the damper by distributing the bending load onto the entire shock body while reducing frictional loads during cornering. I've driven many of my customers' and students' M3s with Clubsport on the race track, and compared to KW Competition, the difference is substantial, especially for more experienced drivers using sticky tires. If you are ever in the area, shoot me a PM

If the Competition netted you 2.8 seconds, the Clubsport 1/2 that? Or are we talking marginal lap time difference between the two?

Just kidding! I also considered sleeve-overs, but decided they are not worth it just to be able to corner balance. Hope 2013 brings you lots of track time and happiness!

Yeah, you are right! Now I'm missing out on COTA. Maybe I can still get on with BMWCCA in June. I'm also signed up for MSR Cresson in Feb. Have fun at COTA and see you at MSRH.

Here's the Houston M Club lap time database FYI. My best time on it was with Continental scrubs or Hoosier R6, KW Competition, StopTech BBK, at about 3,450 lbs w/o driver. http://www.m3post.com/forums/showthread.php?t=605530 Quote:
Look forward to seeing you at our February event!

Very nice compare also helpful. I heard people saying that JRZ RS1 damper and ohlins R&T damper is better than KW CS. Is that true?

I do want to comment a little bit on KW and specifically their Clubsport and Competition lines. As many of you know, on the E9X platform I have hands on experience with H&R coil over, H&R springs, Eibach springs, Dinan stage 1, Moton Street Sport, Moton Clubsport, KW Sleeve Over kit, KW V3, KW Clubsport, and KW Competition. I only recommend what actually works to my customers, and I sell KW because they truly put in a thorough engineering effort (design, analysis, simulation, track testing, etc) on their kits for the M3. When you receive a KW kit, it comes as an engineered, plug and play package. The springs are of the correct lengths and rates, the camber plates will actually fit (and not break) on your car, and the dampers are actually valved specifically for your car/set up. Having a plug and play package means a lot to me and my customers because we want to spend time driving on the race track, and not fiddling with the suspension in the garage. Unfortunately, in the past couple years, partly due to its popularity, there were way too many dealers (authorized and unauthorized) on the market. And many dealers, desperate for business, started heavily discounting KW products. Many sold KW at cost just to move units. And this has led to the perception that KW is somehow a discount product with inferior quality and performance to the other brands. I think KW has been actively trying to address this problem, but it will take a long time to rebuild its brand.

I was previously a Pcar guy. I had a Cayman S. Just a few years back, on Planet-9 forum, KW coilovers were the best you can get and were pretty expensive. If you wanted track handling you get the V3s or CS, if you wanted just a drop you get the PSS9s. Now, coming to the ///M forums, it looks like JRZ/Moton/Ohlins are for superior handling, while KW is just for lowering. Its good to hear that you think highly of KW.. Especially since I just ordered the KW CS Its does seem like a lot of marketing and brand fads that are swaying decisions rather than real performance gains.

You are absolulely right, and it is of pure consequence to consumers now due to certain retailers undermining KW products by selling them at cost or below cost just to move their own inventory. KW Suspension is top shelf grade, especially the Clubsport and Competition line. Having experience with Ohlins (we are their dealer) and JRZ as well, the competition and clubsport KW lines are awesome in comparison and cost less. The best part about buying KW suspension is that not much "user R&D" needs to be done any longer, KW did pretty much all of it. Its mainly up to us car builders to set them up ideally for the driver and car. Malek |
