HELP HELP...... S3 DIFF / SUSPENSION PROBLEM
Can someone help me please??
Its a bit of a long winded story but if you have the time to read this it would be greatly appreciated.
I have just fitted a set of Eibach lowering springs to my 2001 S3. At the same time as having it lowered i also fitted a set of BBS CH reps (8x18 front with 215 40 18, 9x18 rear with 235 40 18) Since fitting the springs i have started to hear/feel a rubbing coming from the car. I originally thought it was brakes as the only way to describe the sound is like a faint rubbing when your pads need replacing. I have been driving for several days and the noise seems to be getting worse. I can now feel the rub through the pedals(especially when braking at low speed) and also when the wheels are turned it seems to be worse.
Around 6 months ago i had the diff oil replaced (as it was grinding and making a similar noise) so im thinking its not that which needs to be replaced again.
I have been told that the rolling radius of wheels can be very important and can effect the diff quite badly if its not correct, as you can see above i have put the sizes of the wheels and tyres ive had fitted, can anyone tell me if this seems ok and if not how to fix it???
Basically ive got noise off the diff which i think may be caused by the wrong rolloing radius and the last thing i want to do is keep driving the car and blow the diff up.
Can anyone help???
Thanks a lot guys
