do it for the noise, not the power.No worries! Like I say, not an expert but I've been modifying and driving my NA for best part of 12 years now, so I'm familiar with what works well and what doesn't with it. You could certainly speak to some suspension manufacturers but for a custom set you'll be into some serious dough I imagine! The Gaz's are probably a really good set, but geared for flat handling and grip instead of slip angle, so might not yield the results you're after. On the plus side P6000's are pennies, especially in 14's so you could probably whack a set on and go at it without much to lose! Sounds like you're after a stiff chassis and soft suspension and low grip tyres which is the opposite of what most people are after so no wonder you're getting funny looks! 😂
As for ITB's, you know they make sense! I'll be getting a set of ZX10r throttle bodies fitted to mine in a few months time which will hopefully take me from 155bhp to somewhere in the region of 170bhp with any luck. And they sound brilliant of course which doesn't hurt!
What engine do you have that's at 155bhp?
