What's that on your hood?

Default question on coilover setup for time attack street class

Hey ya'll

I am looking into setting my car up for the redline time attack street class. I am not new to cars but don't have a lot of knowledge on coilover setups. I have read the infamous unabombers manifesto about coilovers and it gave me a good understanding but still have some questions that I am hoping you guys can help me with.

I am looking for a middle to upper level setup, what are some of your experiences with manufacturers.

Also, rules stipulate only 2 way adjustable coilovers are allowed. What exactly does that mean and what are some products out there that abide by the rules and are high quality.

Thanks in advance for your advice/experiences.

Check out the suspension supersticky in here, specifically the Coilover FAQ. It covers the "2 way adjustable" stuff among other things.

Also check this out:
http://forums.nasioc.com/forums/show....php?t=1701850

You need to decide what % of your car is going to be aimed at time attack and what % of it is street. They are VASTLY different.

Also, the nice folks at TiC and RCE are not going to steer you astray - BUT - you need to figure out your goals first before anyone can give you real advice. Are you still going to DD this car? How much track experience do you have?

I don't want to be offensive, but if you don't know what a 2-way adjustable coilover is you probably shouldn't go buying one for your car. Even though they will be a better option in the long run, not knowing what they are or how to properly tune them is going to leave you confused and upset with a car that isn't performing to its fullest potential. I would recommend going with a higher quality single adjustable coilover with some custom valving. But even then its going to depend on spring rates. Some of the current, readily available single adjustable coilovers my not be setup to use the spring rates you want/need.

What tires are you running? What size? As BD asked, is this a dual purpose car, what percentage each way? As mav1c asked...have you been on a track? How to you rank your skill level?


Its easy to spit out names of some high-end, fantastic coilvers. Finding you a set that best meets your needs, skills, and ability to tune the suspension is a different matter.

I'd expect he'll be on a 255-width AD07, AD08, NT-05, or RE-11.

The big reason I suggest Robi is because he'll be at all the west coast redline events (and probably the eastern ones too), to both race and provide customer support. So not only will he make sure you start with a well setup suspension, if you have questions about it or want to change things, or need some tips on driving and the line, he's right there.

Wow I think I came off as a pretty big robi-whore there, but hey, check out the results for street AWD.

Well then he'll probably be running spring rates in the 500-700lb/in range. In which case he should be running a damper with custom valving as most OTS options are setup for 400-500lb/in springs. For simplicity of damping adjustment I would recommend a set of custom sprung and valved Ohlins Sportlines from Works.

http://www.worksevo.com/store/produc...roducts_id=367

Custom valved KW V3's would work, as would custom valved Koni 8611's, but those are both double adjustable. Even if Robi is at the events to help out, I still maintain that the OP shouldn't be adding parts to his car unless he knows what they are doing and how to adjust them.

Now that's a good question...one thing Nik doesn't mention is that time attack isn't suppose to be from learning how to drive on a track...the street class isn't suppose to be for joe blow off the street wanting to run fast around a track but more for the track enthusiast who still has a street legal car; be it a DD or toy.

I know he does plan to attend at least some of the east coast events. He's offering trailer space to some of the west coast guys that want to head east.

gotta agree with this. if u dont know what it is and you wont know how to tune it, u may even end up with a setting that is slower than stock(bit of an exaggeration, but u get the point)

+1

if you are building a car for street class time attack, i hope u have quite a bit of driving experience and money. most of the AWD cars in street class are pushing over 450whp and have quite a bit of driving experience.

There are a lot of very good single adjustable options that can be custom valved out there....AST and Ohlins come to mind. The AST inverted set-up is a good choice as it leaves you "room to grow" since you can upgrade to the 2 way down the line.

But driving experience should be priority #1. And don't forget brakes!

My point was not to tell you what shocks to buy, or what springs you need, or what other suspension parts you should have etc.

The point is that you should go to someone who knows how to set up the car to be competitive in street class, who is local to you. This way you don't have to worry about all this stuff. You say, hey, here's some money, and you get a car that's ready to race (suspension wise). Then you get to go out there and learn to drive and have fun instead of worrying whether or not you need to turn the bump damping down a half turn or whatever.

Its funny, this suspension philosophy that jamal mentions. Its so prevalent in the Evo community but pretty non-existent in the scooby world. The Scooby world is so much more, roll your sleeves up and wrench and understand your own car. The Evo world is, here's my money, Mueller/Robi, make my car work. I'm personally not a big fan of that line of thinking but there is no denying their results. I can't really stand the tuning camps that people worship. Just not my thing.

Anyway, back on topic, speaking to one of the tuners that have lots of motorsport experience is a great shortcut to getting a quality setup from the get go. No experimenting, just driving and setup. Race Comp, TIC, Robispec are all reputable and will be able to point you in the right direction. Not to mention they are all pretty nice guys with less attitude than some.
