Ok so semi slick tyres and good brakes have got my cars stock suspension really struggling to keep up at the track. The thing pitches and rolls like crazy when I start to push it now and it's frustrating knowing that the car is the limiting factor wheras up until now it was obviously my driving that needed to get better.
This has got me looking for a suspension solution that offers good track focused adjustability while still being as comfortable on the road as is realistically achievable. Ultimately I need something that will make proper use of R-Spec tyres in a supersprint type environment.
My car is a 2010 Mazda3 MPS, 200kW at the wheels, so has all the nuances that FWD cars with decent power tend to share. Longer term plans are to have a Quaife front diff fitted too, but for now the focus is suspension.
I've arrived at 2 options at different price points and am keen to hear some feedback on the gains that people have achieved with comparable setups.
Option 1: Basic adjustable shock absorber (Koni, Bilstien etc) upgrade + Lowered Springs + Camber, Bump Steer, Anti Lift kits
Limited adjustability, performance tapers off after a hot lap or 2, cheap and arguably just as fast as the more expensive options when set up properly.
Option 2: KW V3's + Above mentioned trinketry.
Height, Compression and Rebound adjustable, can withstand a solid 5 lap session before performance tapers off. Obviously the better option, but at twice the cost, is it twice as good?
I guess the first question is, will the more expensive KW setup be quantifiably faster than the cheaper alternatives? It's more tweakable and built to run more consistently for longer, but if it doesn't net any measurable performance gain over the cheap option what's the point?
Any Thoughts? Suspension is a voodoo art at the best of times and a lot of people have some strong opinions on the topic but very few of them have track data to back up their claims. That's ultimately what I want to hear about.
