In MIDIV ITA's greatly outnumber IT7 because of SM cars being entered in ITA. We commonly have regional-National weekend events. Some Spec Miatas are driven in the IT race by the co-driver or the...

I ran a 1st gen RX7 with Hawk Blues for several years without brake problems. Like Scott, I had ISC modified backing plates on the front and collected air from a duct in the air dam. I changed pads...

I used to run a IT7 then sold it. I had a 1980 car with ISC prepared early carb and early intake meaning; 79-80. The flywheel was '82 with matching counterweight. I changed the flywheel and the...

Most of the info posted is basically correct. However, IT7 is a relatively new class that started in 2004 when a bunch of RX7 drivers convinced MIDIV to opt them out of ITA. IT7 started in...

I used to own and drive a 1980 RX7 in ITA/7. It held the MAM track record and I think the new driver holds it now. I believe the car is for sale. Contact David Vandeberg at Sioux Center, IA. He...

I used to race against Scott. My 1st gen had 350 fronts, 175 rears, and the ISC tubular front sway bar, and no rear sway bar. I held the MAM track record for IT7 and the driver who purchased the...

I towed with predecessors to the Express, a 1996 1500 and a 1993 G20, both 2WD conversion vans. The "96 did really well and the '93 was adequate. Both had fuel injected 350 and weighed about 6,000...

I don't know if Mike Vansteenburgh at ISC racing services still does them or not. He did mine and it was great out of the box. It's been used since 1999 without a rebuild, without changing jetting...

Keeping coolant out of thi intake keeps the carb and fuel cooler (less hot) and seems to help performance. I can't say by how much, however.

I too used the Valvoline Synpower for several years without any problem. It is reradily available, inexpensive and has high boiling points and low moisture affinity.

Check the specs on the Valvoline Synthetic brake fluid for brakes and clutch. I've run it for several years without any problem whatsoever. It comes in a big bottle and is cheap but has high boiling...

I don't understand. Do you mean that you can't get the lugs nuts off or that when the lug nuts are off, the wheel won't pull off the hub or is it something else?

I have been racing a 1980 since 1999 and I don't feel it has ever been a detriment. If I were building a new car from scratch I would prefer an 84 or 85 due to more of them still being around and a...

One question that comes to mind is the definition of cheating. If a car being non-compliant is cheating than I suspect that nearly every IT car is cheating. With issues like window washer bottles...

I vote for open wiring in IT. I just don't see where it can make much difference in performance over the open wiring we currently have for plug and distributor wires. Maybe my interpretation of the...

I race at both MAM and Hallett. I agree with the others, Hallett is way more fun, mostly due to the elevation change and blind corners. Both tracks are challenging in their own ways and relatively...

I wouldn't be opposed to a spec tire but it would be very difficult to administer due to the division by division character of the class and the need to run in ITA where IT7 isn't authorized. The...

I suggest going 100% with the ISC setup. Carb, distributor, engine, suspension, exhaust, etc. Mike's parts fit and work and are very strong. I have have had his 3rd arm setup for 5 years without a...

After running a 1st gen for 5 years and seeing what better drivers than me can do with well-prepared cars, I am convinced that the only competition adjustment needed for ITB is 6 inch rims just like...

Please run the IT7 class to keep the participation numbers up. You will probably have a better chance of getting a trophy in ITA however because you might be the only entrant. Since the RX7's went to...

I am from the Midwest Division and was one of the people who got IT7 adopted. We did it because a well-prepared and driven RX7 isn't close to being competitive in ITA against a similarly prepared...

Yes, I'm going to MAM with the car. I don't want to miss your fine meal Friday night. I can use a good getaway and I don't want the car to get as rusty as I am. I also got an awning and might as...

I've been towing a 8x20 enclosed Pace trailer with an ITA Mazda RX7 and lots of spare parts and tires with a Chevy conversion van since 1998 without problems. The engine is 350 vortec. I take out...

If the Oct 9-10 event was a double I'd be there but with towing costs and entry fees being what they are, I just go when I can run two races. In MIDIV we have Regional-National race weekends with a...

Mark, my silver car is listed in the classifieds. I have a complete list of upgrades and photos if you know of anyone who is interested.
