they are cheap but take care their painted ones come through sh*t but the alloy ones seem to be fine but their attitude is bloody awful mate
 
audi sell both of those and they both come as standard on the S3. both fit on the leon cupra. obviously your local friendly VAG specialist will be able to supply and fit these. on the LCR the lower brace comes as standard and i managed to get a brand new upper S3 brace for £20! :p
