Spec C upgrades
 

Can anyone offer advice on the following with regard to 03 Japanese sti 9 Spec C

a) Additional sound proofing
b) Improved ride quality without loosing the handling for serious road use
c) ECU and exhaust upgrades

Any advice would be appreciated

buy an STi gl?

I've added the following to my MY03 SpecC

- Soundproofing foam to deaden the rattle noises (it was really annoying me)
- Ecutek Map & Milltek exhaust with sports Cat & 5" backbox (from Powerstation)
- 18" wheels & AP 6-pots

In terms of the handling, Powerstation & Iain offer a handling upgrade at first which basically involves the anti-roll bars, but you can the AST suspension pack from the Type25 put on there as well.

I think the handling pack is around £500 - £600 and the suspension pack is around the £1200+ mark.

Cheers ;)
