Default More rear negative camber then front??

I just got KW V3 coilovers put on my 996 C2. My ride height is set at X74 height. My front camber is -1.5 and rear is -2.5, is this normal. I was told because of the ride height the front is the most negative camber and the rear is the least amount of negative camber possible. I tract my car about 10-15 day/year and have GT3 sway's with adjustable droplinks. Thanks

I don't think so. I would think the car would want to push with that set up, but I could be wrong, In my GT3 I ran more neg camber up front then rear. about 2.5 front and 2 in the rear. That does not tell you what would work in your car but in your car you need to take out the push.

I run -2.0deg front and 2.5deg rear. I hope this helps.

I don't have GT3 adjustable lower control arm so this is why I can't get any more neg. camber up front. I have my GT3 sways set at 2nd softest out of 4 in the front and in the middle in the rear. Does this sound right? Thanks for any and all info.

The newer cars are different than the older ones, and when optimally setup will have more camber in the front than in the rear. -2.5 in the back is just about the limit of what they want, but -1.5 in the front is sub-par. I setup most 996 track cars with between -2.5 and -3.5 degrees camber in the front, including the '06 GT3 that I had which worked beautifully at -3.2 with 9" front wheels.

BTW if you want more front camber, just buy a set of GT3 strut tops and move the pins. You will get -3 degrees easy, for a lot less than GT3 lower control arms.

You can have more camber in rear even in older cars although I also think your numbers are little suspect but it depends on other things obviously.
I have a 993 and I like tail happy cars but my camber settings are -3 front and -2.8 rear.

Larry you are right that the new ones are not the same as the older cars but more camber in front than the rear is common to both.

Not to add a monkey wrench to everyone's camber speak... But, let us all talk the same language. Camber is based on an angular reading of Degree's THUS, we have all learned from our MATH classes or Engineering programs that a degree is divided into smaller graduations of minutes, then minutes into seconds of a degree (with each sub set totaling 60). Thus, when someone list a setting of -2.5 ... an alignment technician will read that as negative 2 degrees 50 minutes, (-2.8 would be negative 3 degree's 20 minutes). So, when you state you are setting your camber settings at -2.5 or -3.5 you are really stating that the camber settings are -2 degree's 30 minutes / -3 degree's 30 minutes.

It's not "optimal" for handling and tire wear, but probably normal given the stock adjustability (or lack thereof). Ultimately, you'll probably want 1-3 degrees more negative camber up front than the back (struts like camber). 2.5 in the back is probably a good starting point for a street/track car.

Glad we got that straight.

Is this just the maximum camber settings? Yes, you are camber limited with a Carrera in front. Your options are camber plates or GT3 control arms. I would strongly recommend GT3 control arms. I put these on my 996 and you get the added advantage of gaining 1"+ track (depending on shim pack). I had a 10mm shim pack per side which netted -2.4. I had the rear set at -1.9.

If you are running DOT R compounds, you want about neg 2.5 degrees (that would be 2 degrees 30 minutes for the MATH guy above) in front. In the rear about 2.4 degrees negative if you have 11 inch wheels, or 2.2 degrees if you have 12 inch wide wheels.

If we are talking race slicks then around 3 degrees negative in front and around 4 degrees negative in back. A race slick setup makes the car pretty useless on the street though.

Thanks for that Plug... Actually, it gets worse~ the education / occupation is Physicists & Mechanical Engineer and our company designs & builds components for LOLA Racing (1 of our clients).

All electronic camber gauges that I have ever seen read in 10ths of a degree, not minutes of angle.
