I hate the aftermarket ride quality of both H&R & Eibach springs, (the old Weltmeister 928 springs too), so I cut the factory down by about 1.5 coils & then thread the factory-adjustable spring perches down to lower the car about 2.5" or so. It limits the fronts more than the rears as many 928's run newer 996/997 wheels, where the offset is shy at 50mm (factory 928 offset is 65mm), so if the car is high enough, the newer wheels fit "ok".

By re-threading do you mean just rotate with your hand until you reached the desired height? Or did you have to take them off and actually cut a new thread? I've cut so many spring on old VW's that I've had, that it's not even funny! It's actually a cheap but effective way to get the exact desired ride height for your car. What was it about the aftermarket springs that you didn't like? Cutting the factory ones usually stiffens up the rides almost like the aftermarket ones...............at least on the VW's of the past.
BTW if I got 18x10's on the back. Could I run the same tire you are? 285/30? Will the 1/2" make a difference on how the car rides or how it fits on the wheel?

yes, spring perches are adjustable by hand. I cut the spring to both slightly stiffen (does not stiffen as much as H&R, Eibach), and ensure I can lower the car enough.

Yes, 18x10 with a 285/30 is common on the rear of 928's w/o rubbing.

Cool. How about running the 245/35's up front on my 8.5"? Which tire are you running?

I run 245/35-18 on an 18x9 wheel: no issues. Can't recall the offset, but I think it's in the mid 80mm range.

I show no PM's: PM to me or to Dragonfly?

Do you think 18X10's in the rear (295X25) with 65mm offset will work? I want the wide look without having to roll the fenders.

I think so: sounds correct. a 10" rear wheel easily fits (with the correct offset) w/o rollling the fenders.

Mark,

Thanks for sharing your knowledge on these cool cars!

I am on the verge of getting my first 928 after lusting after them most of my life. The car is a 77k mile automatic S4 in Elgin, TX, just east of Austin.

Would you possibly be available for a pre purchase inspection at my expense (obviously)? I am pretty knowledgeable about other marques, but an new to the 928 world...

Regards,

Sanjay

Sure, weekday noon-time would be best for me: I can make a long lunch tripout of it. I can see all I need out of it sitting on the ground & not on a lift. There's nothing as valuable as a pre-purchase inspection, that's for sure.

Thanks for your help, man! Looking forward to meeting you in person!

Great to be a 928S4 owner....thanks to you....

No sweat, my pleasure Sanjay.

If you are in the northeast we would be happy to install one of Mark's kits. It seems to be a very user friendly install, one that could easily be done yourself, but we will do it for you if that's not your thing.
We are SPRY and do anything from simple bolt-ons to full mod on high end cars.
Side note/question: My research shows that the 928 transaxle can't hold much power. Any issues yet? Is what I found true?

928 trans are strong, but with wide slicks, LSD, & the snappy torque of a 6.5l stroker, they can break 1st gear once/twice a year for the racers. Never a heard/reported trans issue with turbocharger kits nor supercharger kits.
