The new, softer SciRocco. Sitting several inches higher, with loads of travel. Also sitting a tad crooked and nose up. OK, more than a tad nose up, maybe an inch and a half. But this is how she runs Sat., because I am out of time. Also still waiting on a replacement wheel, crossed fingers for friday.
I hope for a rough course. :)

How much droop travel do you have? And how much bump?

Looks like droop/sag is about an inch with about three inches to the bump stop. 25% So, if it is like setting up a bike, not to bad. I don't have any adjustment without taking it apart and cutting/welding. I think I am going to need to cut the perches and reweld them lower on the housing to get the front down. I can space the back some, but I will just be taking the sag out of it. We will see how it settles out, I had only driven it a block and had not aligned it when I took the pictures.

Wow. An inch of droop is not... very... much.

My RS and my WRX each have about 4 inches of droop travel. Bump is another few inches, including the bumpstop.

Hope you have some stiff rear springs. :lol:

Regardless, I'd like to get a ride in that to see how it works.

Droop is the amount the suspension settles with the weight of the car on it right?
I have set up lots of bike suspension and aim for about 15% for the racer boys and more for fun riders. I don't have much choice anyway as the car is not coilover, but the VWs are not known for lots of sag anyway. The rear is even tougher because of the beam, there is decent sag if you raise the whole car, not so much if you drop one side. The big sway bar does not help, tho it does help bring the rear around.
At OCS I noticed the car would turn well in the slaloms and the first part of a sweeper, then mid sweeper it would turn into a pig. When I watched the videos, I could see that the suspension was compressing fully, then blam, understeer like crazy.
I hope this will give me better control in the long turns and over the rough stuff in general. There was a spot where it was rough enough it looked like the whole car was bouncing into the air.

that sounds like you weaked the torsion arms to lift it, often, with trucks, if you tweak the torsion beam to lift it highter, you will get no travel goign down, but infinite travel up, and it will drive really odd..

I just removed my autoX susp. and installed a set of GR-2s sprung with the stock springs from a MKII Cabriolet. The rear is a torsion beam of sorts. The rear susp. on watercooled Vdubs is a T beam with a tube welded on each end to hang the hubs on.

One thing you need to watch out for with this setup is when you have the struts almost fully extended (as they are even at rest) and you load them up in a turn, you put more stress on the strut and can break internal stuff. If the springs are soft enough to compress a whole bunch, that won't be much of an issue, I guess. I did see you lifting the inside front tire a lot, though - which is bad for acceleration. :lol:

The suspension I used today on the RS consists of springs from an 07 WRX (mine) and struts from a mad-tizzyte JDM Impreza STi Spec C. Lots of ground clearance, 3" of bump travel, 3.5" of droop, and the springs are soft enough to aborb the bumps while the struts are stiff enough to control the movement really well. Worked great. Had stiffer springs that were about 1/2" lower on it with the same struts before, and it bounced around too much on the slower stuff and would've bottomed out in a few places that this suspension just felt great on.

I am going to look around for some MKI rabbit springs and see what the difference in ride height is. In the front I could lower the perches on the housings. But in the back it would be tougher, the shock has a collar,but to weld it lower with out screwing up the shock would require a TIG, which I don't have.
Anyway, it still works better than Bilstein sports and the very stiff springs I was using(Thayt I now have to put back on for Sanford.
