Since we have adjustable ride height in front and non adjustable in the rear, should I be more concerned with frame angle or rake, then front Porsche specs?
Thanks

Others will surely answer with more details but I think you would want to consider:
1) Front should be high enough that you don't have to deal with bump steer. Seems like RoW Sport, maybe a few mm lower, is about right for your lower limit.
2) Ideally rake is even to about 1 degree down for aerodynamic reasons. Unless you are on the track or doing lots of high speed work on the road, bump steer is a more important consideration.

Hope that helps!

For street use the front should be high enough that you don't curb your car or hook it on parking blocks. My setup is about USA minus 25~30 in the front and about the same in the rear. At this height one must use care on steep drive aprons but only scrape rarely. At this height the car looks good and very very slight bump steering can be felt, not enough to bother with special provisions for it.

The factory provides a selection of spacer rings that fit as part of the top rear strut mount to provide basic height adjustment in the rear. Having said this a nice set of Sport H&R coil-overs complete for the car is about $2000 and can be installed as a DIY job. This kit gives adjustment on all four struts and amounts to a nice upgrade over stock.

I guess I am really saying is the answer is related to how you plan to use your car.

Some comparative info:

Other manufacturers spec frame angle for initial alignment set-up procedures. Didn't know if it is the priority or not. I am looking at the FSD's With ROW M033's as well. This means no rear adjustability, other than spacers... that would raise rear ride height. Really just wondering.

I believe the car comes with one of the spacer rings installed. Not sure if it is the shortest one or not. Half of the spacer is removed and swapped out with a new one to adjust height. The spacer is comprised of two parts the interchangeable part looks a little like a plastic gear ring with odd teeth that locks it in place against a plastic base, the other half. Both parts form the complete spacer.

Not sure how many actually order replacement ones and use them as their are so many fully adjustable strut options out there.

The entire OE design looks like one to lower manufacturing cost as a plain barreled steel strut probably cost less to manufacture then a adjustable aluminium one with a threaded barrel and billet or cast aluminium attachment hardware.
