From your work under specification - duh

Wheels & Tyres
Speedline Corse 10" X 18" ET45mm cast magnesium front wheels 5 x 114.3 PCD
Speedline Corse 11" X 18" ET48mm cast magnesium rear wheels 5 x 114.3 PCD
Yokohama A048 tyres 250/650 18" front, 280/650 18" rear
So what is with the 19 rear?

The cars were lowered, different spring lengths were used. Can give you spring rates if you need them. Currently finishing off adaptive suspension for my Vantage, all controlled by a phone app. Spring rates have been determined for the setup from testing at the Ring.
Yes Please! Would love to see the spring rates. Thanks Kanga!

This is very good news and of course I am quite interested in the spring rates. Between that and their weight I should have an idea what KW tried to do.

Do you know how much they were lowered?

Do you happen to know the motion ratios for the swing arms front and rear?

Do you happen to know the ride frequency of the comp cars and or the road cars ?

We have been working on brake ducts. We looked at several solutions and are building around using the lower grill. The design for the rotor ducts comes from RoushGTR at corner-carvers. He posted this design years ago and I always wanted to try it. It seals the back of the rotor from the chaotic air inside the back of the wheel. This provides a clean air supply such that the cooling rate is even on both sides of the rotor.

We have some difficulties coming, but so far it seems promising. We are going to trying to use fixed tubing inside the liner that attaches to the chassis and screws to the liner with a flange. Flex tubing from the liner flange to the rotor duct.

This will allow us to change pads, fluid, add flex hose, and go to the track.

I sure hope it works

We are on our 2nd revision of the backing plate ducting. Our first version could not be finished. Some years ago I purchased a copy of "Prepare to Win". In it is a section on forming aluminum on a wooden buck. I brought this to Genes attention last week and when I went to see him this morning I was quite surprised and pleased. He modified the backing plate and fabricated a wooden buck for the inlet. It took him some hours with a saw and a sander. We plan to hammer two shapes around it and then weld the halves together, but it may end up taking several pieces. The grill end is not close to being correct, but that should be fairly easy to correct.

Thanks

I am quite fortunate to employ several very gifted fabricators.

Yes - 19 - Stock width - offset to eliminate spacers. I will get dimensions off of boxes tomorrow, but Rich ordered them so I am sure he can tell us what they are -

We cut the buck in half


Then formed around the halves. Eventually we weld the halves together and then to the backing plate.
