We have the Tein SRC at around £3200 but they come with 10kg front, 12kg rear rates and even though the damper is excellent, it will be firm on the street.

A more affordable alternative is the Tein Monosports (which I am still waiting on CSGs input vs Ohlins) which has 8kg front and 9kg rear rates, but the damper is not as good as the SRC and only one way adjustable. These sell at about £1500 which is a bit close to the ohlins really. Again I'd love to hear CSGs opinion of these vs Ohlins as the price is close in the UK.

Thanks for the input. I've managed to track down a supplier for the ohlins for £1823 and the SRC's for £2500.

My budget would ideally be £2000 maximum so the SRC's are a little out of my range. I would also be concerned about their streatability with those spring rates as you said.

Currently using 245/45/17 pilot super sports, going to upgrade brake fluid only for the may track day and see how it goes. Had some decent fade earlier this month.





Yeah, right now I'm aiming for good looks that will be helpful on the track one I actually know how to use it properly.

My first post basically had my entire tracking history. 1 weekend at TWS, 1 weekend at MSR-H, and I'll be at MSR-H again may 16/17th. MSR-H being my hometown track.

Do the brakes first at least (it'll save you money in the long run). After that it's not a huge deal but I personally would do suspension at the same time as aero if it's in your plans.

what do you recommend for coilovers ? rates ? bushing ? diff support ? for better straight line traction and high speed stability ?

thanx

Whoa...okay cool! Well something with a lot of travel in the rear with some decently soft rates. You'll want the ass end up with soft rates to reduce the shock to the tires. Something double adjustable would be good like our RCE T2s or KW V3. And all the bushings ideally.

Let me know and we can talk.

My use is 90% street and 10% track (sprints).

My shortlist is:-

KWV3
KW Clubsport
AST 5100
Ohlins R&T
HKS Hypermax IV GT
HKS Hypermax IV SP
Bilstein B16

The ohlins and the AST's are at the top of my budget and the HKS come in as the cheaper options. For my usage what would you recomend? I run the car in summer on Federal 595RS-R's.

Thanks!

Ohlins are a very good option. Excellent valving, easy to live with, high quality. Capable on street and track (especially on street tires). A little soft out of the box, but not the end of the world with your tires.

KW V3 is an inexpensive 2 way coilover that also does well on street and track. Also a little on the soft side.

KW Clubsport is a great product but I would highly recommend our RCE Tarmac 2 Clubsport instead. They're built by KW (starting from their Clubsports) but to our specs. You also get a lifetime warranty. A little cheaper since they come without their very expensive topmounts. You could then run stock top mounts and get camber from the slotted lower mounts, or add optional camber plates. Great 2 way coilover for the price (though I'm not sure what that price would be shipped to the UK off the top of my head).

I like the Bilsteins...a lot...but the springs are progressive which I'd rather not use on the track. Great on the street though.

AST is quite good but I think there are better values than 5100s. I would not kick them out of bed though...

HKS I have limited experience with.

Double check that the price is with springs (CSG includes springs in their price but a few other places I'd looked did not.) Reports are very good on the ride comfort -I'll find out very soon (this week, once I finish the brakes,) and comfort matters a lot to me for the same reason... If you can swing it, do. Once I realized the price difference was in the range of consumables (tires, brakes) it was an easy decision for me but... Still a lot.

They are about £2500 without springs here in the UK. You can go down to 8kg front, 10kg rear on the SRCs I beleive and bit more range for the CSG.

I'd have the CSG spec if I could but we're talking £3600 landed here in the UK with import taxes. If I can get the standard spec SRC for £2800 with springs I dont think the CSG valving worth £800 ($1200!).

[cjd]

I think 9/10 is the softer setup CSG recommends.

Yes but....

I'm around 250whp, running RE-11a 245r17. I track 4-6 times a year with around 4 autox a year. The rest is daily driving. I live in the Portland area so no salt is used on the roads. Would you recommend the AP Racing Sprint kit with a set of pads for racing and a set of pads for street use or some other setup? A guy that was running the Sprint kit at the track when I was there says it's a night and day difference from stock (not sure if stock for him was with or without track pads on his stock rotors/calipers).

My last track day my car did double duty (2 people shared my car on track taking turns), and my rotors were pretty tore up. The pads Carbotek AX-6 front and rear were great until near the end of the day when the front pads and very noticeably uneven wear with more wear at one end of the pad vs the other. The rotors (stock) also seems warped as the breaks felt like they were pulsing even afterwards on the drive home with normal constant street driving pressure. I swapped the rotors with an extra stock set and the breaks were fine again after also swapping pad onto the stock street pads.

Also eventually thinking about getting a set of racing slicks and another set of cheap wheels, since I can't afford the amazingly light TSW that you guys have on your site.

The Sprint kit would work well for you on street tires, but if/when you move to those racing slicks you may wish you had sprung for the Endurance kit. We ran both and they worked very well at the track. The Endurance kit was a little bit more capable obviously, and if you're serious about moving to slicks or r-comps, then I'd definitely recommend that kit.

Welp, it appears I'm ending up getting coils first. I'm picking up a used set of the CSG spec TEIN SRCs for super cheap.

Which means probably brakes next, so much for appearance now xD

Aww, how'd you pull that off?! Wish I could have, but they're not even available new, and I needed coils, so I went standard spec. Enjoy!

Is there a relation of how much toe will be induced per 1 degree camber?


I wasn't able to find information and was thinking what would happen to the toe if I need to increase the camber at the track.

[troek]

best to just get an alignment, at -3.5 degrees camber my car has slight toe in.
