Re: Front suspension settings and upgrades

Hi Ron
I agree totally with your sentiments and group information into at least 2 categories 1/safety and 2/ Performance. I like to share my info on this forum because I've benefitted from being a member in many ways, friendship,information, parts sourcing etc etc.... There are a lot of entertaining characters who contribute to the site too it's a wonderful thing,what did we do before computers and the Internet?
I had just woken up after a sleep on the couch (it's an age thing), when I
posted on this thread so when I said I shortened the front upper wishbones I should have included that it was to allow the rose joints to screw further in and thus allow more negative camber to be set. Similar thing at the rear to lengthen the lower wishbone/control arm I just screwed out the outer Rose joints. I'm beginning to think a rose joint on the inner end would be better than the sperical bearing I have now as camber and toe changes would require far less disassembly/reassembly which is very time consuming.
Rick when you say you get understeer in a corner when you apply power, I know what you mean and it may mean you have turned too tight a radius and are apexing too early. Anyway I wouldn't immediately blame the car setup beacause the driver can certainly promote this. I would suggest Chris and yourself get onto better tyres as soon as possible because you'll have to go through a new learning curve when you do.Better to do it now because setup changes will be more noticable and corner speed will be faster due to better tyre grip alone. That turn in understeer will probably be gone.
As for the stab the throttle oversteer I find it hard to believe you would be in a low enough gear to have this in a sweeping corner unless you've unsettled the car and the lateral G forces have overcome your grip. This should be much better with good tyres and camber changes too.
I was using Ferodo DS2500 brake pads and The car got too fast and cooked them even with cooling ducts. I'm now using DS3000 on the rear and have a set for the front when new rotors go in over christmas I hope.
