TT lower arms and geometry changes
Carrera2RS:
Chaps, I have done some measuring and I have found the wheel position is notably different with longer bottom arms
Roughly adding 1 degree of negative camber will have the following effects :
Tyre outer edge at the top of the arch will move out by approx 3mm an 14mm at the bottom. The track will increase by 18mm (9mm a side) , the front ride height will drop by 5mm.
Adding 1.5 degress of neg (circa 2 degrees total) :
Tyre outer edge at the top of the arch will move out by approx 5mm an 21mm at the bottom. The track will increase by 26mm (13mm a side) , the front ride height will drop by 7.5mm.
The thread on the control arms is sufficient to cope as the track rod ends will neat to be wound out by a similar amount to the track.
I will see if I can purchase ET50 8 x 18's as the wheel does touch the inner arch occasionally under hard cornering and encountering a bump mid corner. I have ET45 8x18's currently
With circa 2 degrees of neg with ET50's I will be running a front track increase of circa 24mm, 12mm a side :wink:

and i'm running -2,3 degree of negative camber front, maybe that's why my ET48 8,5x19" with 235/35-19" hits occationally :laugh:
Carrera2RS:
at -2.3 degrees, if I read correctly your wheel upper edge will be some 3(offset)+say8(5mm tyre per side and 1" strech)+5 (if lowered and adding 1.5 degrees neg)
So probably some 16mm out at the upper edge !

I deffo have to do something to my inner fenders, with this and my 10mm wider front fenders the inner fenders aren't sitting right. :sad1:
Carrera2RS:
Sounds like you should have plenty of clearance with 10mm extra width. I had no problems running stock bottom arms, 225/40 18's on 8x18 et 45. the will place the outer wheel edge 11mm further out and tyre probably 8-9mm.
My ride heights are now 338F, 323R. They were 335F, 323R before. I was targeting 340F, 325R, they seem to have settled
