Took my car to CG on Saturday for a Porsche Clinic slot with Chris and as always, enjoyable and informative, especially as it was first time there with the GT3. It had been set to factory a few months ago, but obviously CG is another level of scrutiny.
As a result I will be back in a couple of weeks for an inner rod end and toe control arm, plus geo and ride height set up for mainly A/B road use (i.e. not track or grand tourer) and potentially new front springs. I'm happy to take CG's recommendations but do have a couple of questions that people here might have a view on.
The car has been in track mode at some point of its life (CG think this may have been under the care of Fearnsport) and whilst the front top mount holes and arb holes being used now are road mode, there are additional shims on the front that widen the track by 8mm beyond factory each side, which has dropped the ride height by 10mm and may be why the negative camber is nearer 2 degrees rather than the 1.30 I thought it had be set to. CG intend to reduce the shims to factory as they think it unbalances the overall set up with toe etc. (Im not sure of that detail), but I think Ive read that the 7.2 has a wider track and is all the better for it in terms of turn-in and less understeer?
Second question is the front springs which are working fine but have some paint-loss/corrosion at their mounting points. CG say that its up to me to have these replaced or not whilst the car is in as they cannot say when they will break, but that chances are increased, if they do, the geo would need doing again. Im inclined to have them done (it adds £420 to the bill!) but just wondered if it's a little OTT, this type of corrosion is common and cars are fine with it for some time?
Many thanks for any views.
