I need to change up the suspension on my Scirocco.  It has Koni adjustables and Neuspeed race springs on it right now and its the biggest pile of shit suspension I've ever dealt with.  The springs have no where near the spring rate they need for how low it put the car.  I'm almost tucking tire in the front and the bitch will bottom out on the smallest dips, usually smacking my subframe brace on the road. 

I'm looking at putting some bilstein sports on the car since I had those on my Mk3 and liked them.  Also wanted to put ground control coilovers on but I'm not sure what spring rates to get.  I was thinking 450 front and 350 rear. 

I plan on driving the piss out of the car and probably using it for autocross and track events mostly.

Tried whoretex and all i got was "cool"  and "that sounds good, but i don't know anything about spring rates".

i need to put it on scales.  but i believe that stock, out of the box, fully loaded its supposed to be right at about 2200.  Mine has had all the AC stuff removed, all the carpet and interior minus the two front seats and dash pulled out, the rear wing and body kit removed as well, along with the bumpers that were replaced with Mk1 aluminum ones.  I'm assuming it should be right around 2000 or so.  Maybe a little less.  Its going to ultimately be getting a cage and stand alone, so some stuff in the engine bay will get removed and possibly lend itself to a little more lightening.

good to know about the cabby though, i'm thinking about putting some lighter duty ground controls on the Mk1 that I just picked up, i want to get some sort of height adjustment out of it, but i also want to be able to drive it everywhere, all the time, so i'm hoping to get something around the spring rates of a sport spring on that.

I'm planning on using it for autocross and some road course stuff whenever money allows.  I'm not really building it for a class, I'm more or less just building it to be stupid and somewhat competitive in the more open classes.  Its going to be powered by a 2.0 16v with ITBs and cams and shit running on megasquirt most likely so It should have enough power to get the job done.

yeah, pretty much a play car.  once i get it done initially i'll probably go back and make it fit into a class.  I'm not going to be using the car to commute in so it doesn't have to be daily driveable, but being able to drive it on the streets would be a plus.

the rabbit on the other hand, I'd like to put spring rates on it that would allow me to drive it on the streets pretty easily.

yeah I definitely like the flexibility of the GC setups.  I guess I'll stick with 450/350 for now on the scirocco and see what that feels like.  if it sucks i'll just sell off the coils and get something different.

I was thinking of getting some for the rabbit and using OE replacement shocks and just lowering a little for a while and see how that works out since i don't really have the money to be putting full suspensions on both of the cars.  I'm just not sure what kind of spring rates to use to get a sport spring type ride.  anyone know what kind of rates most manufacturers use on their sport springs?  I know must use progressive springs now, so how would that translate into linear rates?

right now i'm running no front bar and the stock scirocco rear.  i found with no front i get a bit more turn in and a lot more grip under throttle while turning.  there is a lot less tendency for the inside front to just start spinning since it isn't being lifted by the sway bar.  also without a front bar it makes the springs work a bit more and puts a little more load on them so you need higher spring rates to compensate for the lack of the bar providing extra spring rate to the suspension... at least thats how it seems to be to the best of my knowledge.

So true, well stated Timmeh.
