Im just wanting to make you aware of the products that ECS/JBR offer for the A4/S4.
The main thing is obviously brake kits. Their kits range from larger discs that use the stock callipers, to the ENORMOUS Stage 4/5 kit which uses the callipers from a Porsche Cayenne and 350mm discs...its as big as they come. Brakes are something that is commonly overlooked when tuning cars but even if you think your brakes are good now, when you have big power (Big turbo guys!) you will sure realise that they are not as good and certainly not upto the job.
ECS Brake kits range from as little as £380 for the OE 2-piece to £1280 for the massive Stage 4 kit. They also offer alot of other products for the A4, so take a look at www.ecstuning.com and if you need prices for anything, just ask!
