1. If there are so many variations of PSK springs based on color coding, why are the Eibach/Audi sport springs "one size fits all".

2. What is the drop from NON-PSK to PSK, and PSK to Sport.

3. Does anyone have the Sport springs, running 17x8 and 245/45-17 tires? Any rubbing?

4. Is there a consensus about replacing the shocks also.

5. If you do have to do the shocks and springs, then isn't a coilover set up a better deal?

6. What is the average install price on coilovers vs just springs.

Thanks in advance for your future consideration

 

<center><img src="http://pictureposter.audiworld.com/17780/dcp00750.jpg"></center><p>I don't know why Audi would use multiple PSK springs - there is only one Eibach part for the Audi accessory spring kit for the 2.7T Quattro. There are other Eibach spring sets for avants, non-quattro's etc.

I've not measured the drop after putting the Eibach's on - it looks like the 1.5" advertised.

I'm using 225/45/17" Michelin Pilot Sport tires - they came with the wheels. If I had bought the tires myself I would have purchased 235/45/17 which do not rub. I don't know that the 245 size would rub but would be pretty worried about it.

The people I spoke with at an aftermarket tuning place and at the dealer where I had the work done was that the shocks would not be necessary unless I was looking for track performance. The recommendation was to stick with the stock shocks with the Eibach springs. Other spring vendors suggest new shocks - Tirerack H&R springs as an example.

Coilovers again were not recommended to me unless I was interested in track performance.

I don't know the install price of coilovers but I would guess it would be close to those of the springs. About $250 for non-dealer or about $350-450 for dealer install for springs plus $99 for an alignment. I'd add an hour to the estimate for coilovers. The job should not be significantly more work.

1. Aud has been fine tuning the suspension. Eibach thinks their spring rate is just fine.

2. Non PSK to PSK is about 20mm. As I rmember, the Eibachs take you another 30mm lower.

3. Don't know. Would depend to some degree on tire shape, wheel and offset.

4. Depends on your expectations. Most folks here have been happy to keep the original shocks as some other shocks could be harsher than they would assoiate with this kind of car. Hemant came from an M3 and I think has gone to both springs and shocks.

5. Coilovers can ride too harsh even when set to highest and softest setting. Also it transmits a little more NVH to the car as well as being harder on the chassis ( squeaks later ). Also, coilovers often do not last as long as the larger and more robust two peice set-up.

6. The springs are quite inexpensive. Labour isn't too bad. Just factor in an alignment as well. H&R as well as Abt have coil-overs. Expect to pay about 1500 plus install.

 

Drop from Non-PSK to Eibach/Sport: 1.5" to 1.75." No good explanation for the variance; I've have the 1.75" drop, with no problems.

Tires: I have Bridgestone PP-02 235/45-17 on 7.5 wheels, with no rubbing problems.

 

The springs also settle for a few months after delivery.

 

I'm running Dunlop 5000's on ATP S5's with the Factory sport springs - it is tight but I've had no rubbing after 13k

Excellent help - thanks
