Theres a set of rpw extractors for sale on here
A set of enkei evo wheels on here aswell
And silver gpx has a set of lowering springs
And ask clint about cams, he got them for his 6a12 lotus elise project from works engineering
If you are looking at cams you should do a port and polish at the same time and bump up the compression also.
Then when that's all done get a piggy back ecu so you can tune it all in.
I got the Works Engineering CAM GEARS.. standard MIVEC cams.
Only after market cams I have heard of are RPW, and i am yet to hear of anyone who has bought them and had a favourable outcome.
Good luck to whoever chooses to be the guinea pig.
I'm not sure if there are on eBay anymore I will look later but I have seen black hks one for 6a12 looked really nice think price was between 300-400 mark
