I've decided to keep my 01 996 C2, S.C. it and work on the supension and audio. The price difference between my C2 and a TT is around 30K and I'd still want to do some mods.

It seems going with PSS10 and H&R sways is a popular option. I've been tracking my car for 4 years and will track my car about 15 days this summer. I have a 2nd set of wheels and I'm buying Nitto NT01's for track tires. PSS10's are around 2K and H&R sways are around 460. Is this my best option for around 2,500 bucks. Do I need to upgrade the droplinks, if I do what brand. Vivid has AP for 200 each, fronts and rears. What do you think of those. I've read problems of them breaking, is this still true? What do you think of the H&R Street Performance coilovers. I can pick up a used set of 4 for 1,000. How do these compare to the PSS10's and are they as adjustable.

I do not want to lower my car very much. I already have scraping problems with driveways, intersections, etc. in Colorado. Which coilover allows you to lower the car for track days, then raise it up for street driving. Should I get an alignment and corner balance.

With 450-475 HP and this suspension, my car will be even more awesome then it already is on the track.

Good looking ride.

Your choices are many:

If your budget would allow I'd get the PSS10 over the H&R any day of the week. Far superior IMO. With the sway bars you will need to buy adjustable droplinks for sure, you want to keep the sway bars "unloaded" at standstill. AP are okay, TRG are pricey but very good, I got my droplinks from www.gocpt.com , they do not list them on the their website but custom make them for their cup car customers. High-quality and cheaper than TRG.

So with PSS10, HR Sway bars and adjustable drop-links with a nice GT3 alignment and you'll be in good shape.

You may want to look into KWV3 as well. Heard they have a bit better damping for the track.




Then later on I'd look into adjustable control arms, toe-links, and thrust bushings to remove all the slop in the standard suspension.

 

C2mojo- nice Motons!

Ken- While not the "popular" choice due to a lack of USA marketing, you may want to seriously consider the KWv3 coilovers. More adjustment options than PSS10, outboard resevior and pretty simple to raise / lower as needed. Making even one or two adjustment clicks for damping or rebound makes a noticeable difference. Full firm is go-kart solid and full soft is oem-like without the washiness. They use a progressive spring and there is also a separate fixed "high-speed bump" valve which soaks up potholes / bumps / track curb etc., which means great for DD use and I absolutely love mine.
Dan at Vivid carries them as well as another 6speed sponsor (check out the thread in the Group Buy forum).

Thanks a lot for the responses. c2mojo, I'll have to contact gocpt to find out how much their droplinks are. p0rsche3, I checked out the group buy and the KW's are only 100 cheaper then Vivids price. I would have thought a group buy would have been a lot lower then that. The Kw V3 are almost 1,000 more then the PSS10's. I'll probably stick with the PSS10's. Does anyone know how easy it is to raise and lower your car with the PSS10's. I already have to be careful on driveways and intersections in CO. I want to be able to lower for the track, then bring it back to almost the level it's at now. Thanks a lot.

 

^ it's worth the extra $ especially if you are going to track as well, and want some convenience factors such as raise / lower it without much fuss. Worth every penny IMO.
Apparently there is not a large margin in the KW's which is probably another reason why they are not distribute widely. Profit margin is king.

Either way do some research and make sure you buy what will fit your needs best, don't base your choice solely on the cheapest priced product. The KW's are probably a stronger performer for the track and I don't think you'd feel like you overpaid.

 

Great color for your pcar, Ig do with KWs, I have em and love em!

 

For $2.5K you may also consider JIC/Cross. They come with adj. camber/monoball on the front struts and monoballs in the rear. These would cost extra otherwise and -1.5 is the max you can get w/o the adj. camber plates. Also, the height can be adjusted independently. Lastly, they also offer many different spring rates and you can mix match to your liking. I have 7kg/11kg. If you don't mind the stiff ride, 8/12 may be the way to go.

BTW, I also considered KW but the cost was already getting up there. I think KWs are in the neighborhood of $3K.

Here's a TRG link with the cost of the monoball kits that would be needed later on if you don't go with JICs.

That'd be close to an extra 1K on top of cost of the coilovers.

 

If your going to SC you should save some money for a brake upgrade too.

 

i disagree... stick with the cheaper street coilovers cuz the kw3s will only get you marginal or net zero benefits as none of these solutions mentioned so far are truly track ready coilovers.

you need to start looking at motons/jrzs/ohlins if you really want to differentiate yourself from the typical aftermarket adjustable street coilovers.

 

I agree with Ben, that's why I suggested PSS10 with Sway Bars. Taking it to the next level is very involved and can get expensive, like $9K+

So if you don't want to spend that kind of dough, the Bilsteins are your best option.

 

This is why I mentioned the JICs. They can be ordered with more aggressive spring rates (than pss9/pss10) and offer the monoballs for the front and rear. Also, they give you adjustable front camber plates that can get you -2.5 (or more) front camber. All this for about 2.5K good price for the features.

Chiming in here. I don't see any need here for adjustable drop links other than to take the preload off the sway bars for corner balancing. If memory serves me correctly the H&R swaybars mounts are in the stock location so you can use your stock droplinks and since the front H&R bar is non adjustable then there is no preload to adjust for... make sense?

 

Sunset quoted me 143 & 154 for GT3 sways and 123/set for droplinks. These sound like great prices, are lighter then H&R. Wouldn't this be a better and less expensive option then H&R. Thanks.

 

Dropping in my 2c-

The KWv3's have a long track-proven history, as well as some very good member history here on the 6.- Which is mainly what cemented my decision to buy them. KW does lots of testing on Nordschlife/Nurburgring and is very active in many different racing events. I don't think the V3's can be categorized with the 'street' coilovers, as they are more designed for track use. The V2's, sure- Those are the "clubsport" variety and built similar to PSS9/10.

IMO if you don't need to spend the coin for JRZ / Moton / $6k price range stuff, the KW's will probably be your best bet for the money. If you were not going to seriously track at all then I'd say yeah go with the PSS9/10 and save a few bucks. I'd also like to throw in that every single KW owner I've read a post from or messaged with has nothing but high praises and 'better than expected' type stuff. Not a single negative comment or even a 'so so' comment, or 'wish I'd bought PSS9/10' comments.

If you want to find out more go to this thread from February - read through the 4-pages- and PM some of the experienced members / sponsors who own and drive on them: https://www.6speedonline.com/forums/showthread.php?t=118595

If you want to download and watch the flash-based 2006 season review of race cars running on KWv3's go here: http://www.kw-gmbh.de/flash/motorsports_2006.htm
KW can also have the V3's customized to your specs id neccessary and their main USA office is located in California. Talk to "speedplay" sponsoring member as he knows quite a bit about the KW's. Off the shelf the V3's should be (from what I've read) more than adequate for anyone short of an expert race driver with fully customized car and needs.

Given all of the info I found, experienced folks I've talked to, etc etc- the $2900 or so price of the KW3's seems to be the best "bang for the buck", a firm cut above the typical street coilovers and a fair price for what you get. I think dealer cost is around $2400US and Euro is killing us, so of course there will not be 'super cheap' deals floating around.

If someone wants to throw down specific info on why the KWv3's are in the same category of coilover as PSS9/10 then please share your experience and knowledge- I'd actually like to know. I have not been able to find any info to that effect. I'd also like to hear any negative feedback on them / use limitations / etc. Have not been able to find info on that either, even looking at other JDM/DTM forums.
