I've been looking into spring rates for coilovers for an A4 1.8T. This is what I've found so far via search. If you want to correct or update anything posted here, please do. Searching this out is a pain in the crack as a lot of conflicting info. F=Front, R-Rear

Stasis Track : F500 R600
Stasis Street : F420 R390
H&R Ultra : F610 R 595
H&R : F450 R 430
Vortrag : F450 R500
Neuspeed Race : F430 R350
Hyperco : F450 R500
APC : F243 R 265


So I'm looking for a street setup that's fairly stiff. I'm starting to think that a F450 R400 setup will likely be good for my tastes on an adjustable dampening coilover. Then I see a few sets with the rear being stiffer then the front. Benefits of this ????

I'm looking for crisp and quick steering response. Suggestions??? Dial in some oversteer or understeer via a suspension upgrade........ I'm not up to speed on what's the natural movement of this car as I just got it. Any adviec from the guru's would be appreciated. It's a 2001 1.8T quattro.

Thanks for the post. I think stiffer springs in the rear will lessen understeer and help the car rotate better through corners. If you have the typical FWD plow, look for something like this. On the other hand, if you're not comfortable getting a little sideways, stay with stiffer springs up front. I'm not saying you'll get sideways with stiff springs out back, but it's easier to get the car a little sideways with stiff springs in back if you try to.
Quick steering response can be obtained with stiff front suspension and tires with stiff sidewalls. Or, you could just get a BMW.

stiffer rear aids rotation.... I have the Vortrag hyperco 450/500s, and I can rotate a bit.

You might consider clarifying which are fixed heights, and which are coilovers.

Fixed Height
Vogtland Sport 1.8T Quattro - 350F / 270R
Vogtland Sport+ 1.8T Quattro - 350F / 360R

A stiffer rear spring helps to promote oversteer.

Any benefit with the stiffer rear springs ??? Still the same rotational benefit?? My quattro knowledge is limited to snow abilities and that's where it all ends !! I have less then zero track experience with quattro.

I had a 2000 BMW 328 sport with a full suspension swap to PSS9, UUC, etc. Yes, handling was a lot different. Sold that and now building a 1969 BMW 2002 for tracking etc. But still want an Audi that handles well. Right now the sport package isn't getting me excited. Kinda numb....... and leans too much. My Audi is quattro....... is that still benefitting from the stiffer rear springs or is that benefit negated somehow??

stiffer rear springs benefit quattro.

How often are you accellerating continuously from entry to exit of a turn? Almost never.

True that......... but I want to !!!

it makes a noticeable difference, both on the track and on the street.
