Default chamber kit = less handling?

i did and search and was reading some threads from a while ago about camber kits. i read one where someoen said that by putting a camber kit in, you'll loose about 75% of handling you gained from your suspension. hope that made sense, but can anyone tell me if thats legit or just talk? he said that the neg camber helps around corners, so when u fix it, handling around corners will be sacrificed. it made sense i guess, but 75%??...reason im asking is i just ordered a kit.

Holy crap, that takes the cake. Doesn't it make more sense that camber is a bad thing, therefore they make kits to eliminate it?

ignorance... to much negative camber is actually bad... Such things as less tire patch on the ground and added strain in the tire from even contact patch pressure really dont help you at all... Typically there is a limit to beneficial camber... Its different for all vehicles due to weight, weight distribution, wheel base, and about 100 other factors...

Generally, I feel most comfortable around -.5 degrees because its negative camber that is beneficial and added tire wear isnt bad.. I would stay within factory specs unless its purely an autocross car or drag car and then thats where R&D come in... Theres alot more too it... But to answer your question. Keep the camber kit.. But have it aligned after!

it's not the camber kit that lessens handling, it's the camber setting that will negate "good handling." the general rule is that negative camber = better handling. For our cars, something around -2.5 degrees of camber is ideal for competitive driving (road racing, a/x, hill climbs, etc). At this setting, you do sacrifice some straight line grip, as well as straight line braking performance--but if you've got -2.5 degrees of camber and you know what you're doing, the grip generated in corners more than outweighs those downsides.

the gripe that negative camber kills tires is contentious. some people think that camber kills tires, but i'm of the mind that even -2.5 degrees of camber doesn't have a major effect on tire life. I've had 2 sets of summer tires last ~20,000-25,000 miles running -1.5 to -2.0 degrees of camber--the key is that i made sure the car was aligned to have ZERO toe at all four corners.

also, camber kits were not made to set cars to 0 degrees camber, they were made to allow tuners to adjust camber settings, front to back and left to right. i.e. my car is dropped fairly evenly but the camber numbers are off by a couple tenths of a degree left to right, a camber kit allows me to set the front camber to -2.0 on both sides, and -1.0 in the rear.

the proper way to methodically set your camber is to test and tune using a pyrometer and take tire temps after a run. using trial and error you come to a point where the camber and total overall alignment yield the best results for what you want to do.

the diagrams are pretty clear. don't know if whatever they wrote is right, though.
