In need of Good suspension and Braking system
Discussion
Dear all,
I hope this mail finds you in good health.
I have had a problem during my last track day and have warped my front discs.
What performance upgrade would you suggest. I have read about the AP racing front discs with the 6 pot caliper. I need them to fit on the standard wheels.
And what about suspension??? What do you recommend?? I have read good praise on the Ohlins. I compete in Sicily for Time attacks and the track is a tad bumpy.
Can you please help me since I have a track day (time attack competition) in less than 3 weeks time.
Regards
Keith

Sadly your unlikely to find calipers on the shelf to fit the car in 3 weeks, the Alcon 6 pot set-up might be available but as yet nobody has bought it. So don't know if they have any on the shelf in anticipation of orders.
However the Alcon 350mm front discs are a good upgrade with Pagid pads. Then you just need to space out your caliper and fit slightly longer bolts, contact Jetstream for the semi floating Alcon disc and Pagid pads.

I have the upgraded 355mm Alcon front discs on mine with stock callipers and mild pads all round and the braking is awesome on track...The Alcon discs are a floating setup and to my knowledge no-one with the Alcon discs has had an issue with discs warping, but many did prior to upgrading.
There are actually more than 1 standard front disc, one warps on track the other tends to be ok IMO...
Cant advise on Shocks, I had the stock setup which was rubbish for hard track work, I now have the Protec's which have proved very good but you will need to spec the springs to suit your style and requirement.

Spec the springs in what way?? From where can I buy these??There are actually more than 1 standard front disc, one warps on track the other tends to be ok IMO...

My main problem is that the track is not optimal and I am getting to little damping effect. Moreover, I have a problem with understeer.... which is funny since this does not seem to be a problem with Nobles right
The m400 (which holowpockets has) has an arb, and these do under steer a little as a result.
The other models dont have an arb and don't underwater on track... Mine certainly doesn't, if yours isn't an m400 it may just need some geometry setup adjustment.
When I say spec the springs. Mean decide what you want before ordering, mine upgraded items were fine on road and track being specd between m400 and gto3 rates... But now I'm finding them a little soft on track for my latest set of mod's hence I'm going to get stiffer ones soon.
So it depends what you want from the car and what model you are starting from :-)

I have a M400. I think i really do need a geometry setup.
The suspension feels a bit too soft. I was thinking about going for Nitron 2 ways or Ohlins. The thing is that I am a rookie at this and am afraid that I would ruin the handling characteristics of the car if i fiddle too much. Moreover, I really need good damping since I am getting too much rebound (and the car is bouncing on track - tbh the track is quite s
tty)With regards to the ARB... should I remove it??? And is it straight forward or do I need modifications

Keith the M400 is a well setup track car as standard, if you are a rookie as stated then l would leave well alone.I have a M400. I think i really do need a geometry setup.

Having said that it shouldn't bounce so you could have a faulty damper / s so maybe you should get them checked & setup as designed.
What I did - send shocks to multimatic (dynamics), told them I was fitting 100lb stiffer springs, (roughly 700lb front and 800lb rear) they will slow down the damping to suit the faster rebounding spring, Dyno test and service, for a very reasonable price. You'll need to arrange it through Jetstream and they'll give you the address and person to send the shocks too.
The car does understeer a bit but brake later and trail brake a bit helps, then turn in later and you can be on power before as soon as you hit the apex.
I'm now at the point where I feel I might need to go stiffer again if I can load up the front ARB so it snaps the link at the end off the bar. Again slightly concerned I loose compliance on rough bits but I'd like less roll in the corners.
I'm sure someone said the previous noble race cars ran upto 1000lb springs.

only problem Graham is stiffer spring will induce more understeer , perhaps a tweek of the rear spring rate and soften the front a bit might help after all most of the body roll is caused by the high center of Gravity at the rear .
Yeah, probably right enough, the rear didn't loose as much as the front end during the diet.
