I know its one of the biggest threads but the great stuff happens from page 8 onwards. It a lot of stuff so read and sink in the info from page one to the last page before you invest in any upgrade as there are a lot of different people who know their stuff all putting their knowledge into one pot and then all that going into the design of the upgrade (which i may add is stiill in development on the diffs) of the ZXR-S. Named rightly so by HKP who is one big collector , racer and model reviewer so knows his stuff.
