I'm running the car low and there was some rubbing on the front wheel arches. Took the car to Chris of 911Bodyshop and he rolled the arch lip for me - so now theres no rubbing there.
However now theres rubbing on 3 points in the wheel arch plastic covers![banghead](https://rennlist.com/forums/graemlins/banghead.gif)
I'm running 18s: 8.5 Front 225/ 40 & 10 Rear 265/35.
Do people tend to adapt the the plastic wheel covers inside the arches?
Pics of ride height to come...

I dont think you mentioned where it rubbed just "at 3 points" and "on full lock with sporty Gs".
Please advise the 3 points?
Please advise the front caster setting? RS Spec is +4deg25'.
Please advise wheel ET on your 8.5" wheel ... 8.5ET??

I'm assuming it is rubbing on the outside front corner of the tyre at the top corner of the front bumper. If so there are two steps required ..
(1.) It looks like your caster settings is incorrect. I could only get about 2deg but that was a big improvement and it really centered the wheel in the arch and noticeably pulled the position on the front wheel back towards the rear of the car.
(2.) Did you grind the corner at metal at the top corner of the front bumpter. I just used an angle grinder and shaved back about 5mm of metal & plastic.
If it only rubs at full lock and the rubbing is on the inside of the tyre, then I wouldn't worry about it.
Someone mentioned the "wheel arches are so full" ... as per my comment above, please confirm caster setting.
Please provide more info.

Frank, does your car have the revised steering rack stops?
These were a factory retrofit that should always be used on cars with 17 in and above wheels (factory doesnt mention anything above 17 as they were never approved)

Link to the TSB, also shows the mod required that SML mentions

I haven't worried about the rubbing on the inside of the tyre during full lock. I never corner at fast speeds at full lock only driving into the garage. If I hear a rub, I just back-off the full-lock slightly.

Reading off the sheet:
Camber:
Left -0°25'
Right -0°24'
Castor 10°:
Left +3°58'
Right +4°02'
I can not remember the offsets, but I believe they were pretty much if not standard. They were a direct replacement. They are Veloce 3.6 replicas. I can find out tomorrow.

Contrary to others I think your wheel position looks fine and indicates the correct amount of caster (see SML's post above for the correct amount - that spec should be on all variants, not just the RS).
Here's a pic of the grinding of the wing/PU join that he mentions (this is advised by Porsche in a TSB).

The damage on the arch you can see above was caused by a second problem in my case which was because the wing stay (rusty bar in above pic) was bent. Once straightened the wing arch came out a few mm and stopped the contact with the tyre. Here it is after fixing:

Rubbing inside the arch against the body work is something you have to live with when running low. I had mine reset to RS + 5 mm to limit some of the rubbing but I still get some:
