Considering getting some RS4 phase 2's but not sure if I should go for 18 or 19"'s It's 1.8T QS B6 Cab I use the car daily to commute to work on the Motorway! approx 50miles a day and where i live are loads of speed bumps and i pick up my daughter from the nannies!! What would be better? what would the ride comfort compare to each other??
