As it ended up, we only got rain wind and cold temps here... a few flurries but nothing stuck to the ground. I got to hit the rug locally, and had a decent day on a new layout with the FT... tapped/grazed a board in the main and broke the steering rack. The car was so decent though i didnt care... i was too busy smiling!!! Track time is helping too... Do you know if you are going to Frederick this Saturday? As long as the weather is good, i can run up there! LMK.

Some advice please.
FTTC4, carpet, rubber tires, after about 4 minutes I begin to loose my rear grip resulting in the tail sometimes breaking out.
My guess is that the rear tires are warming up to a point and loose their traction.
Otherwise the car is great with no binding and there is no tweak (even not after the race), so no problems there.
Got a control tyre (sorex 28) and control inserts and control wheels.

What can I try to not heating up the rear tires too much?
I tried stiffen up the rear springs, but that didn't help (began loosing grip earlier). Didn't went softer, but is there sometjhing else I can try?
TIA

Hello,

Try lowering your rear roll center, green spring on the rear.
Can you give your setup ? It could help to tell you more...

Wov...

I always run with rubber and i've never run with so hard springs.
I don't tell you it's a mistake but it surprise me.
I run with Front : silver-blue, rear : silver-Green.
We only use odorless traction additive.

For the suspension mount, try to lower it on the rear drivetrain.

isn't it too slow in reaction when going to soft on springs?
We drive short twisty track, response is important.
Do you drive on carpet?

Yes i drive on carpet.
We put lighter oil and bigger Hole (#1 pistons with 30 Wt as an example) and found that it give more traction.
May be your track is smaller than mine.

if you run such very hard springs, it may not be surprising that you overheat the tires quickly..
If the suspension "works" more, this will take a lot of heat from the tires.
Did you try also drilling the inside of the wheels with a reamer, this might also help you cool the inserts and the tire in itself..

Hello,

If you can make a feed-back after your tests. It could be interresting to have another point of view.

Thanks

The conditions over here in Australia just don't let the FT TC4's unleash their potential. It sounds like that you guys are getting more from the car over there. I spose it doesn't help that one store in Sydney keeps all their associated gear upstairs where the customers can't view it on the shelf.
As a result, I do have to say that I am changing to a T2. How many others have made the change?

Need suggestions:

FT TC4 On a 90 foot oval. So we are small. I have a few of the new STOCK CO27 motors.

I need suggestions for Spur/Pinion, and color tires. I use Green on front and rear outside, and Orange/purple on inside front rear. I have the final race for points this weekend. I am 1st in sedan and want to win. I got second last week, I just didnt have the power.

Thanks in advance everyone!

Howdy guys. Quick question for the brains around here. I will be running the kits spur, 1 72 I think? What pinion should I use for a V2 10x2 on an assfault really big wide open track?

Thanks.
