TT lower arms and geometry changes
vRSAlex:
There is nothing wrong with running the extra camper. You don't get extra wear issues as long as the toe is set correct. I run 2.5 degs negative front and 2 degs negative rear with no wear problems. I do 50 miles per day too. There are a few m3s we look after that run 4 degs negative at the front!
Top Cat:
Extra camper. :laugh:
I have been runnng well over 2 degrees of camber and have no sign of extra tyre wear whatsoever. :happy2: What i tend to do though is not slow down for roundabouts and the occasional right hand sharp bend. :innocent:

A useful hour or two
The car has now moved to matched front camber at just less than 2 degrees, it was close but slight differences between left and right. Toe now straight ahead and a small correction to rear toe.
Rear camber adjusted down to 1.5 degrees neg (to reduce understeer). The ride heights measured at 335F and 322R. I will probably lift to 340F and 325R this was my target but adjisting cambe then affects ride heights. The geometry will not be affected by a few mm of ride heigh adjustment.
I will also continue to experiment with damper settings and also try different roll bar settings.
The settings of Front ;
2 degrees neg (1 deg 55 mins)
zero toe (parallel)
8 degrees 23mins caster
PSS10 3/10
Roll bar soft
Rear
1.5 degrees neg (1 deg 29 mins)
13 mins toe in (L 6 mins, R 7 mins)
PSS10 4/10
Roll bar hard
All other checks showed the car close to spot on (set back, lateral offset etc)
So far the car feels a little less fidgety, better balanced and less 'front fighting back'. Les understeer and better directionality and confidence.
Not perfect yet, but getting there :happy2:

So compared to your settings mine are
1.47 and 1.33 negative front camber
0.05 toe both sides
8 degrees 36 min caster (LF) and 8 degrees 23 minutes caster (RF)
Rear
1.44 degrees neg and 1.42
10 mins toe in (L 5 mins, R 6 mins)
Fairly similiar in some respects but you are running the more negative camber whic I will need to do to get the benefits from the TT wishbones I presume?
