Just reaching to see if anyone has feedback on these coil-overs? Made in UK and the prices seem reasonable.

That's $2115.25 in USD before shipping, which is going to be spendy from ol blighty

While the Complete Koni setup from Ground-Control is $1899 with the proper top-mount strut mounts to keep the amount of travel decent.

Well proven solution used by the Spec 944 racers:

That sheet shows two sets of coil overs, a street/track day set and a a full race set. I don't believe we would have to pay the VAT of maybe 20%. If that's the case then the race set with the top mount with the current exchange rate of approximately $1.50 would be about $1125 plus shipping.

Ah. I missed that the first time around. That makes the price a bit more reasonable.

Except the strut mount is still not right (reduces travel which is not good on a lowered car, ask me how I know) and how much is shipping?

I have run GAZ for a couple of years(since 2005 i think), though the coilover kits werent around when i built my car. So I have the GAZ adjustable dampers and built my own coiloverstruts. One little detail the rear gaz shocks are far easier to adjust than similar konis, which you have to take of to adjust. In general they have been good and the car is fast on track. I would like to retune them to get a bit increase in low speed damping rate and decrease the high speed area. They can get a bit bumpy on bad roads if you set the damping stiffness for best body roll control.

But the adjusting range is very large though, should fit lots of different usage areas. And the quality seems good after all these years of abuse. How are you gonna use the setup?

Street with occasional autocross use. This 931 is a stock restore but local auto shows give you three mods before your bumped out of stock. Did you delete the rear torsion bars and just go with the coil-overs? I emailed GAZ asking about spring rates. The reply was much like your question "What will you use it for?". I gave the same response and suggested 220 lb. front and 190 lb. rear would probably be good for my purposes. No reply to that yet.

I haven't gotten to a quote yet. Waiting to here what GAZ says on available spring rates. I agree on the strut mounts. Those aren't any more less expensive than the multitude of other camber adjustable mounts available in the US.

My goal is to get the car lower and stiffer without having to deal with torsion bar adjustments. Of course that also involves complete bushing replacement as well.

T bars are not all that bad... Plus you get a tbar merit badge!

Torsion bar adjustments aren't that bad, do it once and then fine tune using the adjustments on the trailing arms. Plus you can refresh all of the bushings while you're in there.

Its pretty well spelled out how to measure everything and get it set correctly the first time.

http://www.944spec.com/944SPEC/technical-articles/42-torsion-bar-re-indexing

Ground Control has notes on spring rates already from their experience with the Spec 944 (which includes the 924S) folks among others. Another reason I'd go that route.

I would have if they had coil overs for the rear back then. But i chose 28mm Tbars from cip1 in the us and 350lbs front springs. Setting corner weight_/ride height etc is not so nice with the excenters, but it works. you save a lot of weight though by throwing the bars out.

If you drive mostly on the street and occasional auto X use a great setup is 250lbs front springs and 25,5 torsion bars at the rear(cheap as hell), or equivalent coil over spring rate. A friend tried that setup on his n/a 76 after my recommendation and it was great. Perfect balance and very adjustable. But requires same size tyres all around, and a bit extra camber up front to be perfect

Except adding coil springs to the rear shocks adds weight higher up than using torsion bars which provides a slightly lower CoG.

It also limits how much tire/wheel you can add to the inside of the rear wheel well, which is important on a 924

It does, but significantly less weight than thick bars which are HEAVY. At least with my wheel sizes the limit of tyre width is the body itself. But sure, tbars are robust and well proven, just not my preferred choice if i had the chance to do the choice again.

GAZ Golds are great with correct spring rates and valving for track/very fast road. Very harsh in low speed and town use on poor roads. Over 60mph on country roads they come alive. If its all town and low speed use and occasional track use, I'd suggest maybe not going full Gold level. My GAZ Golds were supplied and fitted by EMC Motorsport based on their track preparation experience with spring rates and valving set by them, no idea what this was, but it had a track bias versus road use. They mostly retain the TB's versus removing in all their road and race set ups for 924/944/968's. My car was initially set up resting on the TB's with the rear coils as helpers. However the car has now been set up by another suspension geo firm who added another spring to the rear coilover set up so the car sits on the coil springs and the TB is the helper on full compression. The car is now more compliant on the roads.

Over all quality is good, they have been on the car for 6 years with no sign of weeping or issues. When I had the suspension last set up 18 months ago they went on a shock dyno and all was proved to be working well. If something goes wrong they are rebuildable
