Randy from Colorado
Hi everyone, I'm Randy and live in Franktown, CO. I have been road racing for many years in the big bore class. 2 years ago I bought a 1984 RX7 built for the Spec7 class so I had something fun and realtively inexpensive to race in. I can say I have just as much fun racing this little car as I do any of my big bore cars.
I am looking to get some tips from you experienced RX7 guys though. I have moved the Mazda out of the SCCA racing and in to a vintage racing group. Its a little less competitive and more about just having fun racing each other. So the rules are a little looser than Spec7 as far as upgrades. I've done some searching and read the FAQ's but would like some direct feedback:
1-I only get 2-3 race weekends out of a set of front brake rotors. By then they have either cracked or are close to cracking. Will a good set of aftermarket rotors be less prone to cracking like this? I see where KC raceware sells a front replacement rotor. It looks like you can unbolt the rotor from the hub and just replace the rotor if it breaks. Any other recommendations?
2-I usually only get 1 season out of a stock 5 spd tranny, then the 3rd gear synchros start to disintegrate. I begin the slow shift process to make it survive and eventually replace the tranny. I've just about exhausted my stock of spare trannys. I've seen reference to rebuilding one of these trannys using Miata components. What does that involve or are there other recommendations for solving the tranny issue?
3-I need to replace the oem fuel tank with a fuel cell. I can part together something that will work from Summit Racing. But I would like to retain the stock filler location and functionality so I dont have to build a bulkhead in the car to separate the fuel cell from the driver. Does anyone have a recommendation for a mfg and part number of a fuel cell that meets the requirement with minimum modification?
TIA-Randy
