fengshui

I live in the USA and have a USDM 2002 WRX. I was curious to see if anyone over there in the UK has had experience with these specially made tarmac springs from STi. I believe it was an option to the version 6 and the name given to them are tarmac/gymkhana springs(I believe it came with special struts in a package, instead of using the regular version 6 ones). I have not found alot of information regarding these, but I believe I could squeeze them on our version 7 bug eyed rex with some aftermarket struts(koni?). If anyone has any experience with these, your imput would be appreciated.

thanks,

chris
