I am having tyre wear problems with my Coupe Turbo. Im getting uneven tyre wear on ALL 4 tyres!! Its been lowered 30mm all round so i was expecting my tyres to wear slightly more on the inside. But i just had it MOT'd a week ago, and the front tyres i had put on 5 months ago tread read like this, 5mm outside edge and centre and 2mm inside edge !!!! Which is a bit more than slightly wearing more on the inside!! The rears aren't as bad, BUT then to top it off nearside rear got a puncture on monday so i have just forked out £200 on 3 new tyres(replaced the 2 fronts aswell). Obviousy i wanted to get it sorted before i go through another load of tyres, so i rang Courtenay Motorsport for advice, they said that by me lowering it 30mm it shouldn't cause such severe tyre wear and wouldn't necessarily change the suspension's geometry
Which seems strange, if you draw a square(representing a wheel) then a line coming from centre going to the side(representing suspension beam) then from the end of that line draw another line at a slight angle going up back towards the square(wheel) then draw a new square at end of 2nd line at 90degree angle to the 2nd line. Then you will see the edge on the 2nd square thats closest to line(suspension beam) is now closer to the imaginary ground than the other edge.
Surely thats exactly what happens when a car is lowered??? After all geometry is in part the relationship of points, lines and angles, how could having my car lowered not altered the suspensions geometry??!?!?! It would certainly explain the tyre wear issues im having. Also before anyone sais that lowering a car doesn't change the camber, please try the drawing excercise or have a look at these websites(of many) that would dissagree with you.
But anyway, Courtenay recommended taking it to a laser alignment outfit to find out the problem. Then i MAY have to buy the camber adjusment bolts etc, get them fitted and THEN take back to Laser place so they can adjust everything accordingly!!! Obviously doing all that isn't cheap!!
So, now to the point of this thread. In my situation what would you do? Has anyone had the same problem? Should i just get the bolts, get them fitted and adjusted when i get it Laser aligned as its obviously a camber issue??(which is what i think)
I love my car but its starting to test my patience!! OH and cambelts due YEPEEEEEE!!!!!
