I need some new ARBs for my S3, so reading through all the useful info on here 22mm front and 19mm rear is the way to go. That setup can only mean Neuspeed ARBs. I was wondering, if this is a good setup, why then are there not more ARBs of this size by different manufacturers. All the ARBs sold by other manufacturers are much bigger, like the ones from DPM: http://www.dpmperformance.co.uk/audi-s3-8l-99-03-c-2462_2463_2468.html Do manufacturers like H&R actually do and research and development? If they did surely they'd find that their kit of 25mm front and 21mm rear would be creating understeer on the car? Or have things moved on and have H&R found a better setup? Very confused about what to go for?
