coil over setup

Let me talk to them about it. I'll get back to you by the end of the week.

Finally was able to catch Jay at ground control while he was there. He recommends running:

with the torsion bar and see how it works using 300lbs or more fronts and a softer rear to add to the torsion bar. He said if I didn't like how that affected the car I could pull the bar out and run stiffer coils for about 100.00 or so for two.

Since the setup is already built with the stiffened bottom end and the camber plates are ready for a strut brace to be attached, I think I am going to go with this setup here. I need a couple pieces of help though.

I need to know which one of these bolts is the eccentric bolt for the rear height adjustment, he wants to know what the car is set at right now.


I also need to know what things to measure here for the strut bolt distance and the strut flange gap.

Re: your first question, it's the two bolts (with nuts facing you) that have red paint on their tips in the first picture. It looks like you're about centered on the adjustment.

Porch thanks for the input.

Do you know if I have the correct things labeled for the strut bolt distance and flange gap?

the info your may want ?? i think you stated your car started life as a 86 turbo? your t-bar should be a 23.5 MM with a spring rate of 126 lbs . ( i would do a 100lbs rear coil over ) i would NOT opt to low the car by the rear trailing arms ajustments if you want to scale (balance) the car . if you do you take away being able to do any rear ajustments . index the t-bar one spline to low the car . as for the front . from the center of the bolt to the center of the bolt should be 63MM on the late cars with aluminum control arms with a center spacing of 17MM . the center spacing is were the strut slides over the knuckle . on early cars its 57MM from center of the top bolt to the center of the lower bolt and 19MM for its center spacing .

i should ask what anti roll bars are you thinking of using ?

This is just the information that Jay wanted to get me the right setup for my car. Making sure it is not a M30 suspension and what setup is there since the years varied between the suspension and best to know if any of it has been modded yet.

On the front I have a 25.5mm or a 23mm(from my early car) I can use. Not sure what the rear is yet, I have to measure it still.

I was not thinking of lowering my car by the torsion bar,(if I lower it any it will be by the coilover setup) Jay just wanted to know where it is at right now. I was not sure which bolts I should be looking at.

your car if stock will have a 22.5 MM front anti roll bar and a 18MM rear bar .

my car has an 18mm rear sway bar and I have two options for the front. By the measurements I took one bar is off the 1/1985 N/A is a 23mm and the 86 turbo is a 24mm. I used my digital caliper and measured the O.D. of the bars.

you were correct on the spacing of the bolts and everything. I just wanted to check to make sure so the history of the car was known.

cfgioja: did you notice the set of bilstein coilovers on ebay? Probably sprung/dampened too much for the street, but thought i'd mention it.

if your coming up with a 23MM and a 24MM they could be an option bar from porsche ! or your taking the measurements of the anti roll bars with the coating still on them or rust on the bar ? of the bar is a hollow bar then they will be 23MM or 24 MM . if they are solid bars than they will be a 22.5 or a 23.5 bar . porsche does there measurements on the bars before they get a finish put on them .

ah, I see what you are saying. I just cleaned off the dirt and measured the O.D. in the middle of the bar with the paint/coating on them still.
