I'm with Jim and Wally on this one especially confirming that you have a good rear specification. It seems as if the springing is overcoming the damping by a serious amount. Looking at your photos the rear end does not look too low and I see that you have polyurethane bumpstops mounted on the upper bracket rather than the alloy trailing arm but that should not make any difference. i would expect about 40mm+ clearance on the bumpstop at least in the static position. Are the Konis new? and do they work? It has been known for even new dampers of Koni's quality not to work properly. Have you a photo ofv the rear suspension in the static position with the wheel on the ground?

Sorry for the very late reply. So, to give a few answers, the rear is not lowered too much, but still, it is. Today I managed to take a few pictures in a static position, just like you said, but I don't think they are too conclusive. I will try and measure the clearance on the bump stops:
   The konis are brand new, out of the box, and they seem to be working good. From what I understand, you guys think the car is riding on it's bump stops, and only going up/down on it's tires right? That could explain why this effect was a bit atenuated, after I changed the wheels/tires from 195/65R15 to 215/50/17. Lower profile - lower room to bounce around. So I'll try and get a measurement, and maybe cut the bump stops shorter. And for the news: I managed to get a set of 17" Porsche cup3 Turbo twists!! I'm so happy, this was the set of wheels I wanted eaven before I had the bug!!! I got them on the car, with 215's in the rear, and 205's in the front. I was pleased to realise that the 215's fit in front very well, and I could go eaven wider.

Well, the biggest problem is that we don't have a circuit here in Romania.... The second biggest problem is that everytime I do something to my car, it gets less and less practicable on the normal roads, with all the holes, and bumps.... But when you get a few km's of good twisty mountain roads, it's a pleasure. It's like glued to the asphalt, the steering is great also, but it desperately needs more power. And on a straight line, I took it to 160+ km/h with everything stable and good, on the highway, but I think that's all the poor old 1,6 engine can do, eaven with dual webers.
Hope I can throw a type4 engine in this year, but I'm also getting married this year, and that comes first. And I hope I'll solve that bouncing problem in the rear, because it's annoying.

Hi
What sort of tyre pressure are you running, this can make huge difference on the way bug feels over potholes etc? I'm running 20-22 front and 26-28 rear. Steve

Excellent choice the Twists Xellex! They are my favorite too because it gives the beetle an outstanding finishing....!!!
From the photos seems that the bumpstop is too close in the trailing arm and i assume that this is your problem. Before you cut it,just remove it and take the beetle for a ride to see if it repeats the problem again.If not then cut the bumpstop at least the half and you will be ok  Steve, This tyre pressure it is for 17" rims? Because i use for mine 30 for rears and 26 for the fronts, but i dont know if it's the correct one..

Guys, I found this mercedes w123 oil cooler, and I know what you said they are very good for the type4 engines, but this particular one seems to me that is too small for use at least without the stock type4 one too.
I measured 26x9x6cm. Think I should get it? Found a better picture of it on the web too:

hi guys! Check out what I ran into:
I found this Porsche 911 Carrera that was involved in an accident some years ago, and I thought I could use some parts off it, so here I am, the owner of a 911 for the first time in my life  At first, before I bought it, I made a mistake when checking it's serial numbers, and I thought it was a 1987 G50 one, but it turns out it is a 1985 carrera 3,2l, 231hp, with a 915 gearbox.             The engine turns freely, and is complete, but I won't keep it for myself. Gonna try and sell it to get some of the money back. The same goes for most of the parts other than the gearbox and maybe the gauges. And the second thing that I ran into: a picture of my bug taken in 1993 by a previous owner. I knew the bug was white in it's original shape, but I have never seen it like that until now..

I put the car's serial number in the Porsche PET catalogue, and this is what it gave me:
Model designation: Carrera Cabrio Model: 911 Year: 1985 Engine code: 930.20 Transmission code: 915.72 M codes: M197 Stronger Battery M220 Locking differential 40% M395 Light alloy rims, forged, 16 inch M533 Anti-theft device M567 Now, the question is, does this mean the gearbox has a LSD unit installed?

Yes, congrats! But that should also be visible on the tranny itself where the type 915/72 is stamped in (underside, lowest bottom rib) by the addition of '12' with that code. So, should read s/th like 915/72-12 according to porsche's own publications wrt tranny numbers.
40% is quite a lot. Must have been a very sporty driver to order that much. Most LSD's have worn a lot though, but can be renovated with new disks.
