Guys,
Thanks for your input.. We had a perfect track day June 22nd, sunny, dry and 78F... my brother did great and dropped his laptime from 2:08.10 to 2:04.55.
He arrived with his whole family the day before track day.
With the limited time we stuck to the very basics:
- He had ordered a set of Firestone Firehawks, 235/55-17's mounted and balanced on mag rims, got them delivered to my house, mounted them and test drove.
- Flushed old DOT3 brake fluid, replaced with new Ate Typ 200 DOT4.
- Checked alignment, it was adequate - no time to tweak.
- Checked all the systems we could; fuel system, carb adjust, brake drums & liners.
- Monitored tire temps for optimum pressure.
Then we reviewed strategy;
- GOALS: Conserve brakes, use HP and grip to advantage.
- Therefore: Manage the approaches to turns such that he carries momentum, minimizes braking, and then maximizes exit speed.
I rode with him one session halfway through the day.. the Firehawks appear to have fantastic breakaway characteristics, as far as I could tell from the passenger seat: Very gentle onset of throttle-induced oversteer and the transition *out* of the throttle induced oversteer was smooth as silk...
Showing a lot of lean here, but we are very happy with the improvement with so little effort... He made it through the entire day in one piece, had one spin but stayed on track, nothing broke, all good.
Thanks again..
