Hello 6speed Forum Members!

This is car was delivered new with 3 miles to Cantrell and was converted to a street legal cup car.
Mods included:
Cup hubs/centerlocks
Air Jacks

Formula 43 RENN10C Centerlock 18" Wheels
9.0X18 +47mm front 12.0X18 +46mm rear, Clear Anodized (whole wheel)

I'm most likely leaving a few mods out. Contact Colin @ Cantrell Motorsports for more information.

Just curious what makes it a "street legal cup car" A cup car and road car are considerably different cars from engine, gearbox and electronics to many many other parts.
Not trying to call you out- Just trying to get the facts as I am curious how it became a street legal cup car..
We have a shop flooded with Cup cars and have converted many road cars to track spec..
Cool pics of the wheels by the way
So when does this bad boy see some track time? Action shots on track?
Going to Rennsport in Oct?

Yes! First set of 18" 997 Centerlock were installed last Friday. 19" Centerlocks will be available in (3) weeks. Styles available in 18" are the RENN10C997 (radial 10 spoke design) 18" and 19" RAD14 and RAD10 design.
Formula 43 prides itself on quick development and lead times. We manufacture as much as possible in house, including our exclusive German "Spin-Form" 18" and 19" AL6061-T6 rim halves. All manufacturing and assembly is done in our facility in Livonia, MI USA!
Again these new centerlocks were sold and installed by Cantrell Motorsports in Kirkland, WA. www.cantrellmotorsport.com
The blue GT3RS is a car that was recently discussed on 6speed. I wanted to hold off on posting photos of this car because the owner will most likely post comments to an existing link about the car soon. I know that he's enjoying his new GT3RS at a track in the NW right now!

Fabryce,
I shouldn't speak too much about details of the car as my specialty is wheels and again I'm sure I left out many additional mods the car had done.
Colin Cantrell can give you specific details as his shop built the car. You may know him from ALMS, Patron Cup, etc.
I just wanted to share some of the details because it is so unique!

BTW, the finish on the Blue GT3RS is our Stealth Black. We recently developed and tested this for our center sections. It features a low pressure blast to the center and then black anodizing. It has a smooth surface, easy to clean, just soap and water.
