    Oh, I had a Radical SR3. Very expensive fragile POS. Although they will be faster. 12248067_10153137559765951_5192481835168125004_o.jpg

    Wow, nice lap Jeff! I was watching your lateral G - hard to believe you sustain 1- 1.5 like that. I only ever see G above 1 for brief spikes.

    So why do some of you guys have fenders on SRA and others don't? Is it for wet weather or do you like them in dry also?

    The SRA's come without fenders but in order to run with certain organizations you have to have fenders on the car.

    On the subject of tire heat... I could never ever get stock R7 compound to 180* - 220* (optimal per Hoosier whitesheet). The closest I got was 170*, rear only, on 100* day, just after exiting the track with no brake cooling. That's not to say you have to run a tire in its optimal temp range, you can run it at any temperature you want. My conclusion is that the the R7 is a poor fit for the car, unless you want to save money as they'll never wear out. I'm not fast but I'm not slow either, I'm about midpack in advanced groups passing half the Mclarens and half the GT3s.

    Now, if you happen to give up on the stock compound there is a world of really silly gooey sticky purple crack compounds that the Atom loves! Anywhere between R35 to S75 absolutely rocks, and these are compounds you could never drive on for 20 minutes in a production car as they would overheat and wear out in 10 sessions. Not only is the car faster but it's also safer to drive as the braking distance is short out of the pits on cold days. I was able to sustain 1.3G on stock SRA using R35 compound Hoosiers on the 15x7 rims last weekend and that's without getting enough heat in the fronts.

    I've also spun out a bunch of times with no damage. The car has lots of clearance compared to production cars, and especially compared to race cars and Radicals. Spun out at 100mph did about 2 360* and no harm came out of it. It sits high off the ground and there are no fenders or back bumpers to hit things.

    Bike engine pushing 3x bike weight vs. car engine pushing 1/3 Honda car weight! The Atom is the opposite! My biggest knock against Radicals however was the lack of proper h pattern stick shift. I require stick in all my cars. Otherwise I think they are sort of in the same category, 2 person HPDE track monsters.

    Jeff tripped over a photo of your SRA. Whose aero set up are you using.

    Auto Interest is hosting an event over Labor Day weekend at Pitt Race. They run a really great HPDE and allow Atoms. This year they have a whole bunch of other stuff going on which will make for a great weekend. I think it would be cool if we had a group of Atoms show up Anyone interested?

    9and3 - do you know any of the organizers for that event whom I could contact to see if they need instructors? I'd love to get out there (about 5 hours from me) and meet up with you.

    Autointerest typically needs instructors for all Pitt Race events. They are predominantly at Mid O so their instructor base is not as strong at Pitt Race.

    You can go to their website, the guy who heads it up is Jason Kennedy. Reach out to him, I am sure he would love to have you . Also Chin Track Days is mid September and they put on a great event as well.
