Where's the best place for me to look for coilovers for a mk3 Coupe?

Please excuse my dumbness, but i'm new to Polo's/VW

they are not cheap as there hasn't been that much demand for them until recently, there are several companies making them, check the Jackson Tuning forum on here, Philj (owner of Jackson Tuning) will be happy to supply you with coilovers or lowered shocks and springs.

Just beware you'll need to send your old struts off to have them machined/made into coilies.

Amazes me still that no company is prepared to make a serious batch, 10+ would sell instantly i think if not more. Half tempted to try and collect 10 sets of struts and get this done.

main issue is the cost.

i did mine myself and it still cost me £600 by the time i had bought springs, platforms, lockrings, top mounts, dampers, and all the rest of it
