Question: anyone has pics of their cars set between US and ROW ride height?
It currently sits on PSS10 and looks too low for me (just bought the car, see pics).
I'm thinking 150 front and rear (don't like the standard US set up with the front seemingly higher).
Will add FD Hubcentric spacers (5mm rear, 7mm front), based on search results in this forum that should not require longer bolts.
Sorry,I don’t know the specs you are asking about but as far as the ride height in the picture, it looks great to me. I would leave it right where it is. RC
Look good to me as is. Messing with the wheels for a 5MM offset seems trivial. Anywhere between US Height and US -30 = ROW Lowered is fine. Just measure it from the proper points on the suspension and if you change it get an alignment. You just got the car, I would suggest you just drive it a little before tinkering.

Note that the PSS10 has a maximum ride height which is very close to ROW. You may not be able to raise between USA and ROW. Agree with others, car looks great now. If you are worried about bottoming out, use Gert FPB, and be careful to enter dips at an angle.
Have had the car for a 1 month, drove about 600 miles so far. Car handles well (to be fair I don't have a point of reference; last time I drove a 993 was 4 years ago...).
I am just going for the look. Unlike most, I'm not fond of ROW but do think US ride height is a bit high.
My thought for 150 front & rear is to eliminate the front-higher-than-rear visual.
Am not a DIY-er (don't have lift, tools...) and am contend to pay when I bring the car in for an oil/break fluid/tire change in the near future.
Thanks for the inputs. Will post pics if I did the change.
1. Whomever is doing the work knows need to where the correct measuring points are. If they cannot show you the documentation on where the measuring points are then you are at the wrong shop.
2. If you want a 1 degree rake, and it sounds like you do and you should, you cannot have the front and rear heights the same if measured correctly. The rear needs to be approx. 17mm less.
3. As mentioned, you may find it hard to get to ROW height with PSS-10's, let alone higher, in part if you try to corner balance the car, which you should do as part of doing an alignment, which you will need to do if you change the height.
4. Do you have the same 4 tires on the car, other than width?
5. Mileage on car? You may some new suspension bits due to age of the car and/or mileage.

1) I'm taking the car to a local air-cooled specialist that has a good rep on this board.
2) Educate me please: does rake pertain to front ride height vs rear? Is your statement based on the understanding that to achieve a 1 degree higher (rear than front), the rear needs to be approx 17mm less than the front?
3) If PSS10 has no meaningful height adj, then I'll live w/ the car at its current setting.
4) Yes, same tires on all 4 except I'm changing them because, while still have plenty of tread depth, the tires are 10 years old. Am thinking doing the oil/brake fluid/tire/suspension adj done all during the same visit.
5) Approx 45k on odo. As mentioned, I don't feel anything untoward regarding the suspension.
3) Whether it's meaningful depends on one's perspective.
4) Yes please get new tires. My 2 cents, if your getting new tires, get a full proper alignment including corner balance as soon as you get the new tires on. At this time you can also adjust the height without much if any additional cost.
5. At 45K miles and approx. 25 years old, your going to have some aged suspension rubber. See if you have someone local that has mostly if not all new suspension rubber and a proper alignment to give you a drive, it's night and day.

For (3), Bilstein says PSS10 lowers from 1.0" to 1.75" (25.4mm - 44.5mm) . Using the table, this shows maximum height to be 149mm front and 132mm rear, which falls just above ROW Sport. And note all the table readings are +/- 10mm, which accounts for corner balance tweaking and accuracy of measurements. Anything above 149mm and 132mm are not recommended for the PSS10.
OP: If you drop the front-end lower relative to the rear-end in order to achieve a particular look, the handling will be adversely affected. The car will tend to oversteer and tramline. It is best to keep the relative front & rear ride heights within the factory specified range.
