What do you reccomend for an agressive street suspension? Not sure I need a coil over

E82tt6 · 10-10-2008, 10:16 PM

I do AutoX and DE about a dozen times a year, but I'm more of a hobbyist than anything else when it comes to track stuff. The stock setup on the 1 is way too sloppy for me, and I'm looking to tighten it up several notches.

Something slightly stiffer than an E46 M3, perhaps along the lines of a Boxster S is about where I'd like the suspension to be in terms of stiffness and feel. What would be the best way to accomplish this? A quality set of coilovers that I have set up properly once? Or is there a shock/spring/sway setup that would work just as well for me?

I see a lot of highly adjustable kits, and a lot of lowering springs, but I don't need a ton of adjustment, or a ton of lowering. A little lowering to drop the center of gravity is fine, but I'm more about performance than the slammed look. I also don't think I'm going to need to do TOO much adjustment, as I do maybe a dozen autoX/DE events over a summer. I've heard good things about TC Kline, would that fit the bill?

TC Kline won't steer you wrong and they offer great service in my experience. It sounds like you may need a little stiffer spring than what is available from H&R or Eibach, so coilovers may be your best choice as springs are custom from guys like TC Kline or the AST setups from Vorshlag, which also get rave reviews.

Depends on your budget, I say get a set of thicker sway bars first and try some lowering springs on stock shocks/struts, something like Eibach Pro-kit. It will cost relatively less than coilover setup and also increase the limit of handling.

Also, if you don't like the performance then you can always sell the lowering springs and get something else....

TC Kline is a good product, but if you're looking for a good price for an unrivaled coilover system, you want the JIC CROSS Coilovers. They're not about slamming or not about full on adjustability (although it does that this option

), but they are about performance. The ride comfort isn't compromised, but the performance handling of your vehicle is drastically increased. You'll love these. Click here for more in-depth look into these coilovers.

Agreed - you won't get a better system out there if you're serious about driving. KW is a close 2nd.

It sounds like most people agreed to do coil over first and then later decide on the sway bars upgrade, right? I am thinking about going this way since the rear sway bar is a pain to install.

Adrian@jic · 10-23-2008, 01:23 PM

Hello, I work here at JIC/CROSS Suspension Project and would like to give you a bit more information about our suspension solutions to help you make decision. Our coilover uses our own mono-tube design that has been proven on many time attacks. The mono-tube design was developed and manufactured by CROSS/JIC. We do not outsource our products and make sure that they are built to the quality and standard that JIC representatives hold high. The oil used in our damper is designed to tolerate extreme temps keeping the response consistent during extended periods on the track. Rebuilding the Mono-tubes holds no problem as JIC/CROSS/Ziel Motorsports USA carries all products in house to accommodate such requests. Spring rates can also be altered to meet the demands of the consumer. Front upper camber plates are provided to help the end user dial in their footwork. If you have any other specific questions, feel free to email me:

Please choose rear sway bar wisely. Note that if coilover is set too stiff, the addition of the rear sway with no front may cause snap over steer in a corner. We have seen this with Mini owners as they install a rear sway bar but do not have the front to balance it out because of availability. I would suggest you do both at the same time to better tune your suspension.

in the begining of this thread someone mentioned tc kline. i was at octoberfest and was next to those guys all weekend and not only did his cars look sweet parked but they looked good on the track also. my bro was getting his comp license and tc would take one of his cars on the track and mix it up with them and his cars were flat and fast. so i agree you prob cant go wrong with a tc kline set up. i know that is what i want to do.

triggergt · 10-23-2008, 03:00 PM
