I have extensively covered this topic in the past. There are several parts that need to be changed to get the proper front end alignment and rear wheel angles to be oval worthy. Spacers in the shocks will lower them and experimenting with the springs will be fun. Gearing will make all the difference as well.

I just read through your posts and have some questions as to why you do certain things.


While 20* caster blocks might not be the best, I'm thinking 5* blocks aren't either. To get more technical, I'd run the 5* block in the left front only and maybe a 10-15* block in the right front. By taking all of the caster out of the right front you don't allow the truck to gain cross weight (wedge) while it is turning left. That's one of the reasons you prefer toe in, it creates push on turn entery and through out the turn by dragging the left front. The lack of caster also makes the truck want to continue turning off the corner. You've just kindof band aided the setup.


I'd only lower the truck with tire size, getting the arms level and living with the ride height to start, then make small wedge adjustments with the left rear and right rear heights. CoG isn't the biggest factor in handling, roll center is. CoG is only one of the bases for finding the RC.


I've used 0* toe in the rear on a carpet electric truck and the 2.5's for asphalt. Getting foward bite off the turn always worked better for me then trying to reach max speed down the shoot. Actually gaining foward bite would gain exit speed and exit speed carries all the way to the next turn when you use the proper gear.

I'm not sure why you want zero camber anywhere. I race alot of pan car carpet now and I'd kill to be able to put rear camber in these cars like we used to when racing tranny classes. You must be coning tires, is that the reason you swap them around alot? If your coning them, you're not using the tire.

Wardo,
The other threads were for someone that wanted to make a "Street Car" out of an RC10GT.
You are dead on in your setup instructions.
The instructions I gave will put the new RC10gt oval racer close to being able to compete with others quickly. Once they get the dynamics of whats going on they should be able to make adjustments to improve their lap-times. As far as the CG on the RC10GT it does need to be lowered quite a bit for the oval. The foam tires that are available stock for the most part are not low enough to compensate. Most people don't have access to a tire lathe.

I enjoyed reading your post. Please keep the great info coming.

Thanks, I'm hoping I didn't sound like I'm trying to be a jerk, just discussing the topic.


For truck tires I always used to use HPI star wheels, those ones that came with all the adapters for everything imaginable. They were great because when you removed the inner beads on a lathe you could slip the old style pan car donuts for BBS wheels over them with alittle effort then just glue the edges as best as possible. We used to use Aj's/Twinn K blacks. I miss running those classes....

We run an Oval truck class here at our local club. Its a paved track setup in a parking lot. It has grown from 3-4 trucks to over 20 in 3 years and has become one of the most competitive classes of the day.

I had to sit out club races this year due to other commitments and look forward to next season. I did get to race off road this year so all was not lost.

Your knowledge is welcome here. Please feel free to help out whenever possible.
