Terry, I forgot to ask; what have you seen in regards to tread life on those NT-01's, vs the BFG Rivals?

I tend to run with clubs that give us 6 or 7 20-25 minute track sessions in a day, and autocross with a club that holds test and tunes with 60+ runs in a day... I need a tire that will last too!

I am curious about the battery cut-off switch system you have been using:





I really like the idea of the solid state switch, but compared to other solid state switches, it seems like this one doesn't have a 4th pole to cutoff the alternator/ignition. Which most people say i necessary to avoid burning the alternator diodes when turning the switch off.

Can you shed some lights about the wiring ? Looks like you simply cut off the positive pole and that's it. Am I right ?

Vorshlag, I'm glad to see the S197 work continuing!

I have your D-force wheels 18x10. Everyone is telling me I need to run 285/35. Is that the largest tire you recommend for this wheel? Do the 295's bulge bad? That 285/35 is pretty short for Michigan roads.

Guys, in case Mr. Fair does not get the time to answer this soon I did get a response back from Jason, very informative and I decided to stick with the 285/38/18 over the 295/35/18. Damn it! why can't they make a 238/35/18!

"Jeff, we've run the 295/35-18 on the 10" wheels. While they don't get the sidewall support the 275 and 285 see, they work fine, particularly for daily driver use. We had our 2013 GT on them and were very happy with the fit."

Wow, long time to check the posts in this thread. I'm about to "revive" this thread so I will address some of the lingering questions here.

Good point - and we have since changed this setup on Jamie's S197. This old solid state kill shown above from 2013 was not reliable and had a failure.



We replaced this in ~2015 with the solution above, which is a remote triggered, solenoid style kill switch. This electro-mechanical solution is more common from 1990s-2000s. Since then we have found another solid state solution...

This solid state electronic battery isolator form CARTEK linked above addresses the battery, ignition and the alternator. These ARE reliable, meet FIA specs, and have been used in Europe for years with success. We stock and sell these now.

Thanks,
