Got these in today. It's a shame nobody can see these things under the car...

They are gorgeous parts. I got them for my wife's 2000 Boxster S and (even) she thought they looked great.

very very nice.

on a side note, what tyres do you run ?

I need some track tyres and r888 are not the right size
and in the UK you cannot get a lot of makes for some reason.

I still run stock PS2s. I'm not quite ready for track tires. I know bensf is running Nitto NT01s on 18" CCWs on his car.

I know this is an old thread but I'm looking for advice from everyone that posted on it as I am going thru a similar setup process to the above with my CR.

I'm an intermediate driver (average mid 1:50s at LS) with a stock CR with PS2's. 2 days at LS and 1 day at Sonoma so far with this car and the fronts are wearing pretty obviously on the outside edges. Front camber is -1. Rears are wearing fine at -1.6.

Not a daily driver, pretty much just drive to the track and maybe once a week pleasure cruise in the SC mountains. So probably 60% hwy miles and 40% track miles.

I pulled the RSS LCAs off my old 996 and I'm having BRRacing install those on the car next week along with RSS rear toe links. I'm pondering camber set up, Bruce wants to go -2.4 in the front, -2 in the rear. I'm wondering if that is too much given the PS2's. I'm wondering if -2F and -1.6R might be better for my car at this point. My plan is to use up the PS2s and a fairly new set of Yoko AD08Rs until I think I'm fast enough to warrant R comps.

thanks for any advice on camber/alignment specs!

I'm running -2.5 F/-2.3 R (which is about the limit of the stock rear adj) with R-S3's
and the wear is amazingly even with 50% street/50% track....(the street miles like you = to track + weekend)
Imho what wears the inside on the street is when you have camber + toe plus running pressures too high,
if you have little toe in the front and the correct toe in the back with not running pressures too high, the camber doesn't wear the inside as bad as you might think.
The outsides with 2.5/2.3 are wearing just about perfect at the track, even with dropping pressures to find that last bit of time.

No current generation 987 or 997 can have adequate camber up front FOR TRACK DAYS without a 2-piece control arm setup or some way to add camber. The lack of sufficient front camber (sometimes at 1.1 and other times 1.7) will mow off your outside front tire, ESPECIALLY at tracks with long duration fast corners. As far as other mods, the 987.2 Cayman R is capable of having roughly 30rwhp bolted to it without modifying the motor. This is done via exhaust, intake and tuning. Cheers!

DISREGARD ALL OF THIS! Sorry...I had no idea this post was 2 years old! My apologies.

For what it's worth, you just named what I regard as the most well rounded, dual purpose street/track setup for the Cayman for camber. There are lots of people out there that think we don't run enough camber. OH WELL!?!?!?

That's kind of a tough call. It really depends on your driving style. I would agree that -2.0 is the minimum to start off with, which is what I did a few years ago. The only way to tell is to check your tire wear on the outer edge after each track day and adjust from there. After I moved to R comp, I bumped it up to -2.4 and it was not enough, then -2.6, and finally ended up at -2.8 before I ended up with even tire wear (maxed out the rear at -2.4).

Maybe try -2.2 up front and -2.0 in the rear to start with? I think -2.4 is probably your 'goal' on street tires.

LOL. The post threw me for a loop for second until I realized the same!

Thanks John, yeah just sort of lucked into those settings by being limited to 2.5F by class rules and
2.3-2.4R by stock adjusters, but like you said it seems to be a sweet spot for street/track.

Interested to see how -2.5F works this year on NT01's.

Hey BGB,

What are you doing for LCA's for a 981?

the_vetman

Here's been my experience:

-2.4 camber front & rear with 0 toe front and slight toe-in rear. Ran NT-01s for dozens of days and that worked well. My NT-01s lasted for many DE days... IIRC high teens or even 20 before cording. Towards the end I wanted to switch them out but they just kept on going! There was some indication that I may need more negative camber but also some indication maybe I needed less - slightly confusing.

Anyway, "they" told me Hoosiers like more negative camber so I increased negative camber to -2.8 in the front. Well, I corded those USED Hoosiers in 1 day.... OK, strictly speaking, couple of sessions then 1 full day months later. Thankfully I had back up (more used Hoosiers). I noticed outside cording at Road Atlanta at the end of first day with Chin (lots of track time), but when I took the wheels off cording was much worse on the inside. Granted these were used Hoosiers, but that seemed to indicate I need less negative camber in the front. Going back to -2.4 camber front & rear for me.....

Guys, thanks to all for chiming in! Sounds like the general consensus is close to the 2.4F and 2+ rear that Bruce at BRR is recommending so I'll go ahead with settings in that range. He's always done me right in the past but it's always good to see what everyone else is doing as well.

Next track day I'll be rolling with the GT3 MC/stainless lines which I just had done and pfc08's / new fluid all the way around. Add the new camber/alignment settings and it should be all good!

Resurrecting an old thread. I just bought a Cayman R, 5000 miles, one owner, manual, buckets, PSE, Nav, Bose, Xenons, Spot Chrono, and white with black interior. I want to use it for 6-10 track days a year. I used to drive on the track regularly in the 2000s, but not so much since 2009. I am an intermediate driver and want to make a few mods to get it track ready. I'd very much like to here from others with a Cayman R or an S who drive their car on the track. I have the following list so far.

1) RSS Control Arms to allow for more negative camber.
2) 18 Inch wheels.
3) Better tires (but not R Compounds).
4) SRF brake fluid.
5) Numeric Shifter Cables.

Any other mods that I should consider for the first year or two? What are folks using for brake pads? What about the third radiator for extra cooling?

I really appreciate any thoughts. Thanks.
