ARC USA

I've tried lower front than rear and lower rear than front. The car never seemed to like it. It didn't feel balanced to me especially when the traction got higher. I like 0.5 shims all around when traction is high.

Pretty excited!! Starting building my snowbirds car tonight!! Chassis prepped, wet sanded and glued. Spool, diff and shocks done. Can't wait to finish, wish my local track would re-open do I could get some practice time.

I've found that arm sweep may be an advantage even on carpet. Without arm sweep, the car needs more steering input to get the same corner entry. Just didn't feel right at last nights club race. JMO

Jim,
So did you go back to stock arm sweep blocks. I've tried number 2 blocks in the front running parallel no arm sweep and steering entry suffered. I then increased steering ackerman shim from 1mm to 2mm and got it back. Now it has smoother mid corner and exit but didn't sacrifice entry steering.

Hi

What is the max and min amount of teeth spur/pinion? 64 dp

Thanks

sosidge

It's in the region of 99-111 for 48dp, so you're looking at 132 - 148 in 64dp.

So far I've left the 2-2 blocks on the car, I'll be sure to try the 2mm ackerman shims. Thanks

Hey guys, one more thing i have found during practicing is making the wheel base longer in the rear (3mm front and 1mm back) frees up the car and and gives better mid corner. This is with the stock lower chassis on high traction carpet.

making the wheel base longer will free it up? ordered some parts should be here by this weekend Ill post some pics this weekend once everything is installed! Loving the car so far.

On the ARC, i tihnk it has more to do with reducing the driveshaft angle as much as it does the actual wheelbase. I have been running full long (+2mm) for ages now, and the car has been markedly better than in kit trim. I could never get rid of a weird on power push at the kit middle position, and going short, would make the car squirrelly under power.

I'll try that this weekend when I run!!

Debating on whether to put VTX1 or VTX10 speedo in car. Difference is weight. How are you guys on overall weight with the car?

Sorry, electric off road guy at heart. Where are you guys starting with shock oil? From my understanding 350cst can be like 3 different measurements - would most consider that just 35wt?

Thanks guys.

The driveshaft angle is important factor as well and to reduce overall stress is important. Good Point!

Weezy- By moving the rear arms towards the back there is less weight on the rear tires thus allowing the car to rotate and free up the rear. I know it sounds counter intuitive but this is what is felt when driving the car.
