it varies from dealer to dealer, but at worst it will invalidate your warrenty on suspention parts, not the entire car.Blackaeromini said:
there are lowering kits that are warrenty approved like the AC snitzer springs and the JCW coilovers, but both are horrendously expensive.
the AC springs are simply eibachs but rebadged?!?! and cost 3 times as much!!
personally, get eibach springs, there the best solution for value for money i think.
bout 150 2 buy (tops) and free to fit if you've got a bit of nouse! lol
