I had fairly even tire wear on the track with 245/275 setup. If anything, I didn't have enough camber and was not wearing the insides much.

I don't drive enough on the street to notice, and I don't really care either since i drive so few miles, ie.... about 5K a year.

As far as I can tell handling is fine.

I just had the alignment done so I don't have much time in the car. I hope to run a Summit Point Main FATT next week and I'll report back on how the car handles.

I don't drive it on the street much any more so I'm not worried about wearing the inside of the tires. With this much camber I know I'm giving up some straight line braking performance but I think the increased corner speed will make up for it.

Thanks for the reply both Robs.

I rarely drive my car on the street as well and when I do I enjoy the safety of the extra lateral grip. This might be a bit off topic but its something that I am very indecisive. I adjust my wheel alignment for the track according to my tyre wear. It is just something that I've been brought up with and I am not sure if it's entirely correct either My tyre wear, on the track, just reach the outside edge for both front and rear. I feel that I need more corner grip for the rear. Would I automatically gain more lateral grip if I dial in more camber without increasing the tyre size?

I have not had much time to come to the track this year so I have not had a chance to test that out. Much appreciate in advance for expert advices

Let me start with "it depends," but Michelin says about its Sport Pilot Cup R compound tire, "Negative camber should be targeted between 1.5 and 3 degrees (with a maximum of 4 degrees) on road courses." So you probably would get additional lateral grip with more camber as long as you don't exceed 3 degrees.

Keep in mind that you will give up some straight line braking performance with additional camber.

Rob, sorry I havent't read your write up in detail, but you should be able to easily get more camber than that, like more than -6*. At mid setting I got around -3*. Are you sure you didn't install them backwards? Others have made this mistake. You want the offset oriented so the top of the wheel can go further in than out.

Also, I'd add that you should be very careful when torquing the nut so you dont't strip it on the outside , as it is a very flat nut.

rlaifatt,

I didn't try for max camber in the front. With a stock setting of -1 degrees of camber I had -3.2 degrees after the SPC install. Using the stock adjusters I could have added more camber but I only wanted -2.8 up front (1/2 degree less than in the rear). Michelin recommends -1.5 to -3 degrees for the Sport Pilot Cup tire anyway.

I'm sure I didn't install the SPC ball joints backwards (which would be for adding positive camber for the totally slammed S2000). Also, SPC describes the ball joint as good for +- 1.5 degrees (see the SPC install instructions posted on the How To web page).

I'll add a warning about rounding off the top nut.

I drove the car for about 20 miles today on twisty back roads. The car handles well and is surprisingly stable. The extra caster seems to add more steering center feel. I'll give you guys more feedback after I get the car on the track.

Rob, I only responded because in the last line you said you had the SPC set for max neg. camber (full in), yet you also said you had -2.8* camber, so it sounded like that that's the max. you could get. The SPC's on the S2000 can easily give way more than -3*, probably -6* or more. Doesn't matter anyway if you only want -2.8* and you got it.

Has anyone that's installed these had any problems with contact in the wheel well from compression?

rlaifatt,

I have the SPC ball joints set for max negative camber, but the stock adjusters aren't anywhere near max. With my setup you can get more caster. The more negative camber you set with the stock adjusters the less caster you can get because they both move the lower control arm.
