Track Junkies- What suspension are you using?

Please post what suspension system you are running.

I post here rather than the suspension forum because I wanted to avoid the

"I looks slammed" discussions. I want track-tested options. Please chime in.

I've heard bad things lately about the KWs.

Thanks!

TC Kline DAs with M3 front end and Vorshlag plates. All of this thanks to Harold at HP Autowerks. He's like my pusher man ; ) .

Had UUC sways when I installed them but I wish I had the stock sways.

They make me feel fast but don't know if I am but I do know my car loves Infineon; even with the stock brakes.

Did it take you some time to dial in the TC Kines?

I'm looking at the PSS10s, BMW performance and TC Klines. Is there a reason why you chose the Bilsteins?

The adjustability of the PSS9 stinks on this application. I had the PSS9s on my last Audi and it was very easy to adjust without removing anything on the car. The E90 is completely different. If the PSS10 improves on this I would consider them. However, based on everything that has happened in the last year..and what I now know..I would put the TC Kline stuff as the front runner.

Whats the bad things you've heard about KW lately?

I am running the KW V2 and honestly, i do not think they are as bad as what ppl say
they are. Yes the spring rates are a tad bit on the softer side but I feel my car handles
pretty good and definately enjoy playing with those modded subbies

I just got in the new AST/Swift setup from Harold - haven't driven it much at all yet but am gonna be auto-xing it this weekend - Harold likes it even more than his TCKline setup. I stayed with the stock strut mounts because I do commute in my e92. Also did the m3 front kit, m3 sways front and rear and m3 rear guide rods. Very happy thus far.

I'm running JIC Cross coil-overs and UUC adjustable sway bars. They are 15 way adjustable and react REALLY fast. It's like night and day difference from stock. On the track they were set up neutral to a little understeer (i.e. safe), but you can adjust them the way you want. Soften up the front and tighten up the rear and you'll have oversteer. Once I hit the curves on the track, anything with stock suspension was left far behind. 335s, RS6, G35 it didn't matter with the hp difference. Stopping and turning is much more important on the track.
The way the suspension system is set-up, you can change ride height, but it doesn't affect the spring rate.
I highly recommend this set-up. You can adjust everything. The c/o's come with camber plates too.
In the track pick, I'm completely hooked in the corner. The car is very flat and easy to balance.

In the Brake and Suspension forum, there a few threads.

Thanks for the input! I'm leaning TCKline now.

I dont think you can wrong between the ASTs and the TCKlines - they are actually down the street here in Santa Barbara and use good Koni shocks. Main difference being the twin tube design of the konis versus the monotube design of the asts - I usually go with bilsteins and thus prefer the monotube design.

With all due respect, you sound like an advertisement.

I have the TCK with camber plates. They are phenomenal on track.

The springs that come with TCK are a bit soft (400lb/500lb) for dedicated track use but are a great street/track combo setup. I run over 20days a year and I still haven't felt the need to get stiffer springs.

The camber plates are GREAT on track. I get there, unbolt a few 10mm nuts and slam it to -3.5 degrees in front. I drilled a tiny hole into the top adjuster so I can use a pick to adjust the compression. The strut bar gets in the way, so you can't use the plastic koni adjuster.

The bad about the plates is that they clunk on the street. Probably on track too, but I don't notice anything but the doppler effect when I zoom by the Poorshas in the corners The metal bearing improves feel dramatically but transmits more noise.

It is a price I am willing to pay. With a square setup and the negative camber up front, my car is easy to throttle steer and the front tires don't get destroyed.

Good info, I may be sold on the TCK. Too bad the camber plates clunk on the street, but having -3 camber up front would be great.

You can get them directly from TC Kline racing
http://www.tcklineracing.com/

You can call and speak with TC himself who is very helpful.

Also Harold @ HP sells TC Klines. We discussed the TC Klines and I ended up ordering the AST SA set up from him. I worked with him to custom tailor the set (spring rate/height). He brings a lot of 335 experience to the conversation.

The spring rates seem a bit high compared to most others, but on the street they are completely livable. There is no noise at all with this set-up either. It's less harsh than an e92 M3 set in sport mode. At the track they are fantastic.

And no, I'm not advertising anything. He asked about c/o's so I gave him my review. I'm thinking he's going to be getting a ton of responses from PSS9/10, TC Kline and KW owners. I may be the only one who chimes in on this suspension set-up.

btw, this is a great thread discussing TCKlines and AST with people that really ARE track junkies - mostly e36/e46 guys, but there are a few e90 guys that chime in too.

You know I run TCkline DAs on the coupe, and you've seen first hand what that does.

Oh and you know who sells them too, better get them from us

So what is this though? You thinking of keeping the car now?

Sorry, I've been away a bit. I like the TC Kline setup but would make sure to get them from and have them installed by someone who really knows them. This goes with any suspension upgrade. Read Harold at HP Autowerks.

I have the car setup well but it took a bit. Mainly, that's cause I'm a little lazy. My suspension far out does my tires, brakes and cooling system.

BTW. The UUC sways should not be considered an upgrade. They are far too stiff and disallow a lot of mechanical grip. I know from experience. You may feel faster but just be honest with yourself, you're only flatter. They are a ridiculous upgrade/downgrade.

I understand the TC Kline camber plates do not clunk like the Vorshlags. The TC Klines also naturally allow for more camber than the Vorshlag which are limited to below -3 on th eE9#. You can get more camber if you have the M3 wisbones on the front.

Hope this helps.

I would do suspension before going to R compounds on the track.
