MG ZR: Cams & Maps

[lolsteve]

Steve, I've told you... That suspension is garbage... It needs replacing asap! Always welcome at jp's garage!

Power wise, I agree with you. If you couldn't keep up with the mx5 last weekend then it certainly needs more gogo.

Now you are up this way, let's get it on the dyno and start tuning...

Cheers man, after you mentioned it I began to notice it more. Will check under the car tomorrow see if I can get a look at the rear shocks, as swear I recall them having scrap yard writing on them.
Needing a remap now, perhaps the mapping will not so much up the peak power but make it more reactive i.e remove throttle lag which saw someone mention gets removed a bit from the standard mapping after a z&f

It does feel pretty under-damped Steve, and your brakes were fading pretty badly when I was on track with you. Is it standard suspension? Try some uprated dampers, preferably adjustable, because I'd definitely say the damping is the problem. And bin those budgets, tyres are the most important thing, its like Usain Bolt running the 100 metres in flip flops

Standard dampers with lowering springs, thing is it's weird the standard shocks on the zr are meant to be uprated a bit like gti6 ones I guess, perhaps they've aged too much? Did feel quite a bit of body roll this time around so maybe they've reached their time.There isn't any after market shocks for these which is proper annoying not even oem level replacements. Well there is but they tend to be more expensive than coilovers of which there are two options AVO or Gaz, neither as you can guess are very affordable

it is really surprising a different/ good set of tyres can transform the handling of the car
i have experiance with this at the nurburg ring after running my road tyres back to back with a set of A048's

with a good set of tyres you will probably lay off the brakes more and not cook them
maybe just upgrading the fluid to race fluid would help a lot it has on mine

Was really giving the brakes hell this time pushing everything to the limit to try and keep up. Think racing fluid will be the way to go so I'm not having to bleed the brakes every time, does it like need warming up to work well like racing pads?
