The OPTIMA Batteries OneLapCamaro - Final Preparations

[Payton King]

post all of this up and it is very well documented.

Looking forward to many more updates during the race.

What sizing did you end up on the front for a master? I know your pedal ratio and piston sizes are probably different than mine, but I ended up .70 front and .75 rear after 2.5 years of messing with mine.

We're actually opposite of that - 0.75" in the front and 0.70" in the rear. Set up like that the bias control is "neutral" and we can dial in more or less front or rear if needed.

Hi James,

Awesome mods! I just got my zr1 hubs too...

Just a couple of questions:

What new wheels are you getting?? and any pics?

Also, what color and product is the bottom of your car sprayed?? ....wheelwells, pans, etc.

Thanks!

[James OLC]

Tires arrived today...



Hopefully wheels are not far behind!

I wish I had my new hubs - I ordered them three weeks ago and today, after hounding them for a tracking number, they admit they they don't have any in stock (despite telling me that they did). If you don't mind, PM me your source, if it's different maybe I can still find a pair in time.

The wheels are new Rushforth Night Trains - dark Titnanium centers with brushed hoops. Can't wait!

The bottom of the car was sprayed with a reduced rock guard (nothing special just thinned out) and then just single stage grey.

PM sent, James.

What sizes are those PS2's?

[James OLC]

Sadly - same source.

The rears are 335/30-18s and the fronts are 275/35-18s - should be a nice improvement, especially on the front.

275 on the front really what is the BS for the wheels you are still using the stock "ATS: frame right

[James OLC]

Front wheels are 18 x 9 with 6.4" of backspacing.

As I have said before - what works on the OLC may not work on an other car and I do not recommend trying to do the same without testing it on your own car first.

When we first mocked up the car, I bought a dirt cheap 18 x 8.5" wheel from summit with 6.25" BS and used those to test clearance and fit. With the exception of the outer tie rod end clearance we had no issues. With the extra 0.15" we may need to increase the steering stops a touch but we will cross that bridge when we get to it.

Subframe is "stock" ATS - SpeedTech.

Here are some new photos of recent repairs to OLC.
Radiator plug was leaking and galled, had to drill it out and chase the threads.


New petcock installed.


Reverse solenoid was not working, found a bent terminal on the left hand side of the photo. This will be a big relief!
