I've read around about super beetle struts being the same for 924's but when I cross check part numbers they don't match. Has anyone had any experience with ordering beetle struts? I only ask because I know someone who has a ton of beetle parts and I can probally get some for cheap from him.

beetles 52-79 have rear shock absorbers that will fit our 924s

They have a 12mm eye each end and the distance between the bolt holes are approx 425mm to the centers

the bushes are narrower though you will need some 1/2" washers either side to stop lateral movement but the work well. I have been running them for the last year an a half.

very interesting

do you use them combined with the torsion bars? what does it do when you use both the torsion bars and these coilovers? Does the handling improve or just get really stiff/uncomfortable?
Would be fun if you could use these instead of torsion bars, but my intuition tells me they are too small/loose for the whole weight. On the other hand, a beatle probably has more weight in the back and doesn't use torsion bars (right?).

Yes i use them in combination with my stock torsion bars. This is how they are designed to be used in the beetle and transporter. The beetle has almost identical rear axial as the 924 and uses the torsion bar setup to support both an engine and gearbox in the beetle. (Hmmmm.... weren't the 924 and beetle axial designed by the same bloke ) These coilovers are meant as a replacement for the beetle stock shocks (without coils) to give it a more sporting feel. Yes, they do stiffen up the back end of a 924 but without much discomfort. There are 3 preload settings, i have mine set to the hardest. It feels like someone has glued my car to the road. but then i am using them in conjunction with the stock torsion bars and am using 968 struts (designed to support a 3litre engine) up front.

I used the SSP (Street Style Power) version http://www.vwheritage.com/ssp/Shock-Absorbers/?templateID=ssp cheap way to make a big difference. But thats just my opinion. I don't know anyone else that has done it.

they are about 12mm shorter than the stock shock so you need to load the spring plate a little to get them on. I just placed a jack under the control arm and lifted it a little below the hub. I will post some pics if you like

Edit: remember, if you are running 944 aluminum control arms (1985 onwards) the bottom fixing is 14mm not 12mm so you will either have to make a spacer for the control arm or push the bottom bush out and find one that will fit to give you a 14mm fixing,

Front suspension is actually Rabbit based and the rear is super beetle based.

For cheap HD torsion bars, check out CIP1.com:

http://www2.cip1.com/searchresults.asp?cat=739

should be under the off-road section.

cool!
although on the plus side of the coilovers over uprated torsion bars, they were fitted and working and i was driving the car around within an hour of receiving delivery of them.

Although i do my own repairs and upgrades, i would much sooner be driving it than taking it apart.

thanks! but if they're shorter, won't that stress the coilovers a lot? (on bumps or whatever, when the wheel goes max out)

its only by about 12mm and technically yes, if your wheels leave the ground.
but for a street car, i haven't had a problem.

I'll keep it in mind anyway seems a cheaper option compared to bilstein shocks.

well...think of it...you get new shocks....plus stiffer rear suspension...without taking the torsion bars out...which IS A MAJOR PAIN IN THE ASS.

you get 968 stiffness (that sounds weird) with 1-2 hours easy work of changing the shocks on your car.

i'm going to try them...i have wide 968 rear suspension and i'm going to replace the bushings in these shocks with the ones from the old shocks.

Having just done the torsion bar and aluminum trailing arm swap on my car, I'd have to say that you're being a bit melodramatic. I just have to ask, have you actually done this yourself or have you just read about it online? Just curious as it makes a difference to where you're speaking from.

Personally, I think I could do it in a day with an extra pair of hands to help with the heavy lifting. Doing it on my own, it took me a couple of days start to finish and that includes wire brushing and painting some of the parts (watching paint dry)

It really isn't much harder than swapping the rear suspension in a solid axle car (compare setting the pinion depth to getting the torsion bars at the correct angle)

You're still going to have to do the alignment, but that's after the car is moved around a bit anyway.... So you schedule that for sometime during the week after it is back together.

9XX Girl: How much did it affect ride height? I assume the ride height increased a bit as they take a bit of the load off the torsion bars.

morghen the beetle rear shocks have a narrower bush. I put about 3 of 1/2" washers either-side of them to stop lateral movement. Also, there is no guarantee that the later bushes will fit these new coilovers. Yes the inside diameter is 14mm instead of 12mm but do the later 944 bushes have the same outside diameter as the 924 or even these beetle ones. I would be inclined to have some spacers turned that have a 12mm hole in but have a 14mm step in one end (instead of the washers) that will then fit the 944 later control arm mount (if you access a lathe), this would mean better interchangeability for later replacement, (very important for me as it is my main transport and i can't afford the car to be out of use for more than 24hours)
Give me a couple of days and i will post some pics and some bottom bush dimensions, then you will know.

fiat22turbo, thats OK if everything comes apart easily. Prior to this mod i tried to prep the car for a torsion bar swap and discovered that one of the large bushes that fix the beam to the car has a frozen bolt. The Bolt, 900 082 059 02 (M12 x 115) ones that go through the big bush is corroded to the bush inner sleeve. Not enough space to cut the head off and drive out. Gas Axe job and will result in a bush replacement (not the cheapest of items), anyup, its there and doing the job so why change it before i have to.
Also, this set up allows for some stiffness adjustment quickly and easily and shares the work load of the torsion bars.
968 M030 spec used the idea of sprung shocks on the later models so even Porsche saw a benefit... look...


356speedster yes this mod increases ride hight but not to the extent that it can't be adjusted out on the 36mm eccentric adjuster

Edit, I would be interested to see how others get on with this set-up as, to my knowledge, i don't know anyone else that has done this.
