I just put on 911 struts on my car. When let the car back on the ground it looked alot higher than before. Is anything that is different in size with the 911 struts? How can I lower the car more? I believe that the torsion bars have already been fully adjusted to the lowest setting. I'll post pics later.

reindex the torsion bar cap......

Oh ya, do the shock inserts have anything to do with the hieght?

Installing high pressure gas shocks will raise the ride height.
So if your struts have Bilsteins and the old ones didn't that is the reason your car sits higher.
Did you roll the car back and forth after letting it down? Sometimes it takes some movement to get the car to settle into it's proper stance.

My 911 struts are koni i believe. I reused my 914 kyb shock inserts because they seemed to be in better shape the my 911 koni inserts. Would that account for the raised hieght?

If they're not high pressure gas they won't influence the ride height.
What kind of bushings do the a-arms have? If stock, the car may take a bit of driving to re-settle into position after having them at full droop for a while.

KYB's are gas (I believe)

I agree with the punk... reindex. Did you follow the factory procedure upon installation? If'n I recall.

With cap off, use a pry bar to pull the a-arm completely down in it's travel. Install the cap indexed as far up as possible. Lower car on suspension and adjust.

im nobody's punk

Does anybody know if the Kill Yer Back shocks are appropriate for any given set of 911 struts? They may not be fitting the struts correctly... I'm not at all sure!!

I believe that only Koni inserts fit Koni struts. I would be very suspicious of how the inserts fit into the strut.

Are the strut housings (where the insert goes into - has the spindle on it) Black Red Or Green?

If they are black (Boge) then there are various inserts that fit a boge housing (billstein, koni, boge/sachs, mulholland, KYB's)
if they are red (koni) then ONLY A KONI INSERT WILL FIT

The kyb's fit in fine, no problems at all, but under further inspection I think that my koni's are fine to use so i think im gonna try those out.

Can someone tell me the procedure for reindexing the torsion bars

I dont know what the original strut color is since they have been repainted.

ha, and yes Aaron I know what a strut housing is

Actually, they make Koni, Bilstein, and everything else to fit into a Boge strut housing.

The KYB inserts are intended to be used with Boge struts, which were originally black and say "Boge" with a 911 part number on them.

What probably happened is that you replaced some old Koni hydraulic struts with gas charged KYBs and it raised the ride height a couple inches. The car will also sit high until you drive it and it settles down again.

scrape off some paint on the back side and report back what color they are!

or give me the embossed part number off the koni strut? are they "special D's"?

Yeah, I know, but I said Koni strut [housing] [sic].

Koni makes 2 inserts:
1) Fits original Koni Strut housings 2) Insert to fit Boge housing

Likewise Bilstein
1) Fits Bilstein green strut 2) fits boge strut
(*also available in HD or Sport models - to my knowledge, sports have a shorter rod made for lowered cars)

Boge made just boge inserts......

along with KYB and Mullhollands

I thought KYBs are Low pressure gas, which does not affect ride height noticeably.

I just checked and they are Boge struts.

then all is well in the land of OZ.....


PUT THE KONIS BACK IN!

this may sound stupid but did you roll the car back and fourth after you let it down to get the bind out of the suspension? WHen you let it down the wheels are in farther than normal and need to be settled by moving the car around. IT will make the car sit slightly higher.

Ha, ya I think that will be alot better. The only reason I put the KYBs in was because I thought my Konis were bad, but thats not a problem anymore.

So does anybody have any instructions on reindexing the torsion bars?

Hey xsboost, nice avatar ya got there!
I've got her on my wall lookin' over my shoulder.

Adustments

I did a search and this will help you raise and lower your front beyond the current lowest point.

you can find instructions for re-indexing the torsion bars in this thread...
