smart ass..


"look at me, I'm a qualitfied engineer..."

Yea, but it won't help ou next week on the kart track!

This is only true for equal length parallel wishbones, which bascially no one wants or needs.

You actually want neg camber gain(on the working wheel) as your chassis rolls around a corner.

Imagine your chassis is rolling 5 degrees in cornering(not too out of reach for a golf lol) and ur set up with neg 2.5, if your wheel only moves up and down in the same arc your result will be positive 2.5 degrees on the outside wheel. Which equals not nice handling.

You can get all sorts of results from changing the wishbone lengths angles and king pin inclination of a vehicle, obviously it's not cheap or easy to do so. And as we know everything is a compromise.

Got me there.

I took a shot

I took a shot

Were you there in the SLK? I do remeber seeing an SLK in the parking..

Yes, late in the day took a few shots from the last couple of groups. There were some quick cars and a mixed bag as well.

Cool that actually makes me look fast! Got any more?

Just so you know, you can hear your wife say "sh*t" about 5:10mins in..

Good clean, smooth lines from what i could see. Very nice.

Good to see you're starting at 90% and working your way up instead of 125% and working your way back..

She also drops the F word when she tripped over the tripod a second time

I'm trying hard to concentrate on technique for the moment.

Did you spot the puff of smoke from the car on the last entry to turn 1?

I found the LHS tyres were running colder than the RHS ones due to all the LH turns.

Next time out at Sandown I might run 1-2 PSI lower on the inside and see if I can get the temps to even out. I was running 24 PSI cold (8degrees) all round (Before anyone tells me I should be running 40+ PSI - These are semi slicks - street tyre logic does not apply ) and aiming for around 30 PSI hot.

No i missed the puff. I take it you want to lower the pressure so that the tyre carcass moves around a bit more and creates some more heat? You could also try running a higher pressure to decrease the contact area a little. If you decrease it, that smaller area gets hotter faster, and it also has less surface area to dissipate the heat back into the track.
