Gt12 USA Spec
#274

Locally we are doing:
USGT motor
SJT rubber
750g
56/72 or 49/63 gearing
Open diff/spool
Open body
Breakout time, based on who shows up and what we agree on. This is what makes it the most fun for us.

The question wasn't directed at me.. I admire the persistence though. I was hoping we could focus on having a universal GT12 spec class that made sense for everyone, but we can keep giving bullfrog a hard time if it brings everyone joy 🤣

Go ahead -My statement is race what your local tracks support- In these times you need to keep them going otherwise you have a shelf queen. Simple it you race carpet or down here we race outdoors whatever floats your boat. Ya'll have a Merry Christmas and a Happier New Year.

12th GT has become the biggest class in Southwest Ohio. We started with the SJT rubber tires but had lots of quality issues. We set up a foam class that took off well and we gave up on the SJT tires after not getting any responses or resolution. We run Reedy fixed timing 21.5, spec foam tires, 78 spur, 45 pinion, GT body. Gives everyone new something specific to buy.

All of the current spec tires are a 38 shore I believe, originally designed to work on ozite. I'd still like to see a spec foam that's 50-60 and rock hard like black used to be. Something hard enough to have to lift for corners instead of being wide open all race, be able to run them much bigger, and no dumbass glue.

Between the Halloween classic and the indoor champs is what 3-4 weeks? And you burned through a set of set tires to the rim? How many runs by guess did this take? We’re you shaving them? Burning them in? Seems to be the aspect that the rubber tire was hinging on, longevity, is quickly being taken to the standard run style associated with foam

There were a lot of laps on them. Not just weekend race days but a pair of test days as well. No sanding or truing. It was the fronts only and that is the ones that go first. The camber was off a little to boot so blame that on me. Believe me at the level I run that would have been several sets of foams.
fair enough, that’s actual fair. Just struck me as odd, fair bit of laps though makes sense.
