As pointed out cutting the bump stops won’t improve ride quality in case of Audi’s 20 mm sport supension. In fact full length yellow bump stops are a technical must with these Audi sports springs, because of the applied combination of
- non shortened dampers and
- linear spring characteristic.
In addition these Audi dampers unfortunately offer much too weak compression damping. They neither do harmonise well with Audi sport springs nor would they avoid potential packing of the springs (with shortened bump stops).
Generally without their original length, the bump stops won’t protect the bottom of the damper!
However, shortening these buffers is highly recommended for lowering rates of 40 mm and more, but only if combined with shortened sport dampers (also with so called rebound dampers). Now the shortened damper rod cannot smash the bottom of the damper cartridge.
Coilovers are a different animal though. In contrary to the above mentioned widely used combos consisting of lowering sport springs plus shortened sport dampers coilovers provide identical residual spring travel over a quite large range of lowering. Accordingly often the original bump stop length can still be used with coilovers. For that reason the coilover option can supply more comfort than a regular sport lowering (provided same amount of lowering).

So if you still want to keep your Audi sport springs, just combine them with the fantastic Koni FSD dampers to remarkably gain ride comfort. Check out the “comfortable” FSD-thread!
Even better would be the combo 30/30 mm WEITEC springs plus FSD. The more progressive spring characteristics of the Weitecs work better than Audi sport suspension springs on a lightweight car like the A2 in terms of comfort. The set of high quality Weitec springs costs only about 110 EUR.
, please do not recommend buying Audi stock SE dampers!
