Lowered 986

[The Radium King]

are you sure it is camber that is destroying your tires? is the wear just on the inside of the tire, or all the way across?

camber should be relatively static with height change. it might go a bit more negative as you lower - strut at slight angle will pull top of wheel carrier in as you lower which will create negative camber and wear inside of tires. coffin arm as it rotates upward when lowering will will push bottom of wheel carrier out and create more negative camber which will wear inside of tires. but go low enough and coffin arms pass horizontal and start to pull bottom of wheel carrier in and reduce negative camber.

most people want more negative camber for better performance.

then there is toe. as you lower, oem toe control arms - which are not adjustable - will cause toe to go out of spec which will scrub your rear tires. standard practice is to get adjustable rear toe control arms so that toe can be put back in spec on a lowered car.

i'd be you money that your problem is toe and not camber.

+ 1 on Radium comments..

When you lower your car, you need to use adjustable toe links as the OEM rear toe links does not have enough adjustment and that will chew the rear tires pretty quick

I installed a set of Rennline rear links on my 987 CS, and later move them to my 981 but the issue with those is that when they wear they start to rattle, and that was driving me nuts as the pavement on my association is not smooth.. so two weeks ago I replace them with a new set of Tarett's now no more rattle :-)

If the rattle does not bother you, you can have my old ones for $110 shipped, please let me know if you want a picture of them.
