revalving shocks

Another thing to consider is whether or not to make the springs progressive, that is, using a "tender" spring, or to make them single rate, or using a "helper" spring. A progressive rate will make street driving much more civil, but will require a little more time for the car to take a "set" in a turn on the track. I switched from tender springs with rates of around #250 to helpers, with essentially #0. My car is mostly a track car, and I noticed the difference immediately, and greatly prefer it. I have 800/1000 mains. Their are posts in the archives in the Racing Forum for anyone who is interested in this, and possibly here as well.

This is wild... I can't imagine why anyone would spend the money on Motons or JRZ if the revalve is so cheap. $400 vs $5000 and all you get are some adjustment ***** that all but the racing engineers will know how to adjust....

It would be best to drive both before you decide which is for you. I've had Motons on my last 2 cars, and love them. For me, the adjustments made a huge difference. No doubt, there is also a huge difference in cost as well. As I said above, tenders vs. helpers also make a huge difference. Nittos vs. slicks (or even R6s)...the list goes on.

After driving the last event I can say that the car is much faster with the revalved shocks, but would be even faster with multi-way adjustables. There are some spots on the track that having fast bump/rebound would be VERY helpful (i.e., curbing and rumble strips). But for the most part, car balance is much improved all the way around, which is a big plus.

It's like the power seat option. Set it once and you're done.

Has anybody revalved at Bilstein in Europe (which country) and what were the cost then approximately ?
Does a car need to be re-aligned after the shocks are revalved or replaced ?
What type of Bilsteins were originally installed on a 2004 GT3 ? PSS9 ?

I can't see how you can pull the suspension apart, change the springs and shocks and NOT align.. Not the place to cut corners anyway. last summer I had to replace a worn rear link and had the car aligned without giving it a second thought.
Odds are, your alignment is knocked off before anyway.. Its easier than most realize (the degree maybe doesn't matter quite as much on the street, but absolutely does on the track). I align a couple of times a track season - especially because I do drive on the street.

Yes, much less expensive to revalve vs. Motons. However, you need to consider alignment, removing/installation, possibly new springs so the real price is $2,000- $3,000 and the results are very good.

However, when comparing to other upgrades, I only consider the first $2000 as any suspension change would incur the same (or a bit more) cost for install, alignment and corner balance. So around $2000 [all in] vs $5000 [just shocks!] for motons.

For OEM springs what's the general re-valving specs? Apparently my fronts are blown so I"m just going to send all 4 in this week. Do I need to get new springs? Even worth it?

You need to check with a well informed tech to be sure but I "think"stock is 250/450.If you track the car suggest you look thru this thread and see what folks have done I am at 800/1000 right now and I like a firm ride on the street and use the car mostly on the track but those rates aren't troublesome to me on the street.
