Setting up ride height
Ok, pulling a few things together from a couple threads on ride height - want to be sure I get this right.
Stock GT3 height is (couldn't find RS):
F. 108mm +5mm -0mm
R. 133mm +5 -0mm
This is measured from:
Front: Road contact surface to lower edge of hexagon-head bolt of cross-member screw connection to body.
Rear: Road contact surface to the locating bore in the rear-axle side section (between toe and camber eccentrics.)
Recommended rake is 10-15mm.
My question is - what is the factory rake at those heights? I need a reference so that we can get it right. Can I get some pointers on how to setup the rake?
Many Thanks

133-108 = 25 - this is your rake number.
Currious where you got recommended rake of 10-15 from?
Apples to oranges maybe, 996 cars suggested height only calls for 13mm of rake in stock form but most increase rake to 20+ mm for track work to help with rotation / balance. Curious why on your 997 you'd be reducing rake where in 996 world we all try to increase it.
Here's images of the measurement points:
Tip I've always found helpful. It's nearly impossible to get a measuring device into where you need to measure. I usually take wooden dowel rods and cut them to the length I want my ride height to be and use them like a feeler gauge between the floor and that measuring height until it's right where I want it.

Is 133 - 108 in the manual for a 3.8RS? Sorry I dont have one here.
My car new arrived 149 - 108
And if Orbit measures the correct way my ride height last couple of years was 137 - 98. Seems to work fine.

108/133 is for the .1RS
102/137 for the .2RS
102/142 for the 4.0
