Thumbs up Experience with GFL billet upper a-arm

I recently had a four-wheel alignment done on my S2000, and was able to get -2.5 camber in front and -3.5 camber in the rear. I would like to get a bit more negative camber in the front. Does anyone have experience with the GFL upper a-arm? Based on the part description I could go up to -6 camber!

Maybe, maybe not. It depends a lot on your ride height. The GFL part has some clearance issues with the shock at the bottom of the travel.

At least it does on my car, but with the history of my car (major crash), whenever a part doesn't fit quite right I always wonder if my car is just a little tweaked in that location.

I was only able to get -2.5 camber in front with the GFL part (stock suspension otherwise). That was about -1 more than I was able to get with the OEM arm.

So, the amount of negative camber is directly proportional to the ride height? Here are some pics showing my current ride height:




Is there another camber kit out there you'd recommend? I have a Hotchkis rear camber kit on my wife's Civic and it is a very nice piece.

Yes. The lower it is, the more negative the camber will be. In fact, for really slammed cars the concern is usually getting more positive camber.

This is part of the design, since when the car is cornering you want the compressed side to have negative camber and the uncompressed side to have positive camber. That way you get a flatter contact patch.

Why would you want more positive camber? Tire wear? I thought that, in terms of handling, the more negative camber the better. Of course you suffer more tire wear, but you gotta pay to play.

Negative camber is only a means to an end (a flat contact patch while cornering). You can have camber that is too negative just like you can have camber that is too positive.

Thanks for your input.

BTW...would you consider 375/324 or 324/375 (cannot remember specific combo) to be a fairly soft spring?

Either one is a soft setup.

The GFL arms added about 1 degree. If you remove the easy camber adjuster washer and screw it all the way down (and locktite it) you can get another .5 degree. I'm running -4 and thats just about maximum.

Hmmm...I wonder if I should look at having my Koni's revalved so that I could run a stiffer spring, or hold-off until I get a better suspension setup (which would be a year or so down the road).
