[Fot] My Video from the Kastner Cup

Dear Bob,

 

I know how hard is to work on bad habbits. I do this all the time myself.

 

If I approach a corner I brake and short before turning in I shift down gears to be easy on the drivetrain and the engine and not unsettling the car.

See my mistake last year at Dijon when I damaged the IMSA TR8 when I unsettled the car on downshift in the rain on slicks and lost it.

 

I use on the TR4 original calipers with the cheapest type brake disc from the Bastuck company. They last long.

As brake pad I use Pagid racing pads with RSL1 compund. I get along one season with a set of pads and about 8 seasons on the discs.

 

Cheers

Chris

I have no issues with the steering wheel so I've never fixed it, but I look at it every time I sit in the car and think I should. I tend to use the engine to help braking way too much, and after this experience at Lime Rock, and watching myself screw up,  I spent my next racing weekend at Eagles Canyon focusing on not using engine braking, with some success. Old habits die hard.

 

I just can't get myself to trust the brakes on this car. The pulsating I get through the front pads is pretty extreme so I find myself overreacting. I should just give in and replace the heavy B Series calipers with later TR6 ones, but the car is so original I have kept it that way.

 

After the Lime Rock weekend I looked at the brakes and should probably have replaced the rotors but decided to get one more weekend out of them.  After the ECR weekend, which is much harder on the brakes than LRP, I went through the brakes. The Carbotech front pads had eaten through a third set of rotors and they are still only halfway used up, and the rear shoe friction materials were all beginning to crack. They must be made of granite. I've got a set of Porterfields ordered to replace them. 

 

All the best,

Bob

Cool racing!

 

What would disturb me a lot is the left pointing of the steering wheel.

And save your engine on down shifts…..far too high revs bothering the engine without any need.

 

Cheers

I've finally got my video uploaded from the Kastner Cup. Never having been to Lime Rock previously I foolishly skipped the Test and Tune session and I tried to shorten the learning curve. I think I started 24th and ended up 15th, so you'll see me passing and being passed!
