What if I order the longest ones as I'm not against hiring up the car. The 140mm for rear and the 85mm for front ?
What are the consequences on comfort and road handling ?
Are they still compatible whith Koni FSD set?
Hello,
I assume you want to keep the standard length stock Audi springs for maximum comfort w/ Koni FSD?
Highly recommended are the
SPIDAN front springs (#49515 for the TDIs) to avoid future breaking of the front springs.
For all A2s except for the 1.2 the
- front bump stop # 8Z0 412 301
- rear bump stop # 6Q0 512 131 B
will be correct and can be ordered through any VAG dealer.
The length of these yellow rubber bump stops has
not to be changed if you maintain standard car height!
Only if using sport lowering springs you have to shorten these rubbers by the amount of lowering (for example 30 mm lowering springs demand 30 mm cutting).
Applying longer bump stops than stock is counter-productive because then the free spring travel is reduced resulting in
- less comfort
- less road-holding
- less traction
- less grip
- longer breaking distance
- and NO height increase at all because the springs do determine the car's height primarily.
Please remind.
These bump stops should only be active in case of very deep potholes to protect the damper's internals (valves) from getting destroyed during bottoming. So during 99% of their lifetime the bump stops should stay inactive, just sitting there.
As for the front top strut bearing, at your actual mileage you should change the entire assembly meaning seat plus ball-bearing:
P.S. I strongly recommend to buy the above mentioned
SPIDAN front springs substituting the Audi standard front springs prone to break frequently.
You will notice a 10 mm increase of car height at the front in case of Koni FSD due to their gas-pressure setup and strong compression damping characteristics. That lifting effect would be fine according to your statement...
