Fellow Rennlisters,

I have fianlly found a workshop here in the U.A.E. that can do a corner weight balance!

Actually the workshop that prepares the rally driver Mohamed Bin Sulayem's race cars and private car collection which consists of F40, F50, Porsche GT1, Merc CLK GTR etc. etc. so they should know what they are doing.

Therefore I would really appreciate if anyone of you guys who might have the wheel allignment and corner weight balance data for the Euro RS and standard Carrera 4, would be willing to share it with me.

I don't have the numbers handy, but they're in Bruce Anderson's 911 Performance Handbook. He lists the information as Euro RS alignment specs--make sure you use the ones for the 964 as the 993 numbers are also in the same section. The standard specs can be found at <a href="http://www.porsche964.co.uk/technical/tyres_etc_.htm" target="_blank">John Miles' website.</a>

As for corner balance specs, I've never come across any, HOWEVER, I believe that front and rear values will be a function of the ride height, and from side to side, the object is to get the numbers within 20 lbs(?) of one another. These adjustments should be carried out with a half tank of fuel and driver in place with seat in normal driving position. Also, make sure there's nothing extra in the car.

Perhaps someone can clarify/elaborate on the corner balancing issue.

 

Hey Joey,

I would really appreciate if you could get me the Euro RS data since I dont habe BAs handbook.
