Pictures of 928Turbosports turbo kit installation

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.

Thanks Mark. I wish I had a good reliable mechanic in Dallas. I have a bunch of questions for you regarding your turbo install. I'm on the fence between SC (twin screw) and single turbo. What type of FI system would you use if you had it to do over again, and why? Would you consider helping me with an install. I would pay you of course!

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.

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.
