STi Time Attack 2008 - new dyno figures !!

Do you normally drop tyre pressures to go on track :?:

I thought with most road going tyres you up the pressures slighty to stiffen the sidewalls otherwise they end up scrubbing the tarmac and making the handling a bit squishy and steering slow to react :-k

or am i more than likely completely wrong

Thats correct - but these will be track tyres with stiffer sidewalls and are designed to run at lower pressures.

I didn't know that!!

Glad to see you're using the Toyo R888, i've never used them but i hear they are very good and you seem to find them on lots of track cars like Caterham and Lotus.

Nice one :thumb:

depends on the tyres, the car etc.
For the road legal slicks i would always drop the pressures, plus once you've done a lap or two, the heat builds up and i will see around 5 psi increase due to this.

A decision has been made and going with.....



Exedy Twin Plate

So that should take care of that

Good Choice

Good Choice

yeah - it is just not worth taking the risk on something else.

This way I should be up for the BigPower 1/4 mile nights too

Whiteline Camber Bolts fitted this morning. Pretty easy job but left geometry undisturbed for the mo (as best I could)

While I was doing this I dropped the front of the car by 8mm to level it off with the rear.

Templates for canards created - not sure whether I am actually going to fit them but we will see I will cut them out this afternoon and see what they look like

I have also made the measurements for gurney flap to fit to the rear spoiler and calculations for the drawings made :thumb: That should be interesting

edited with canards cut out of the carbon sheet:

[duncan]

- Nomex Balaclava
- Nomex Socks
- FIA Roll Cage padding
- Aerocatches
- looooooads of 80mm ID brake ducting (if anyone needs any please let me know I will have loads spare !!!)
- some misc aerotek nuts and bolts that are always handy to have in the tool kit.
- some yellow electrical tape for the negative terminal on the battery

on their way to me....

- Corbeau Sprint seat from Mr APT
- Bride rails from Japan
- Roll Cage from Japan

Car goes in for the open heart transplant on Tuesday - I cant wait !!!!

Thanks to all suppliers for getting everything to me in time and for putting up with endless changes of mind (especially Mike Tuckwood & Jase)
