I've just put a short review of the CRC super soft sensor wire up on www.carsrcracing.co.uk.

Hey Yang, were are my tires????

Well why don't you just call it super stock as it's defined by ROAR:confused: why not call it what the class is, or do you think that may cause confussion to the masses?

I'm just asking... I'm not trying to insult you or get insulted, I think Chris and Yang have done that enough for the last couple of days:D

I'm working on it... I have a couple of lipo's on order, I still have some round cells but they may be a little iffy on the performance scale. I've been running 1/8 scale at HT. I think I'll be able to come up to SRS in a couple of weeks.

I've heard rummors that CH may pull the carpet and go to asphalt or myabe just start running the offroad wet to keeep the dust down. We'll see.

I just ran some numbers on those rollouts. Holly cow those are some big pinons. I was kind of expecting that but wow.

I am planning on running a CRC Gen X. What is the smallest spur you can get on one of these. Also anyone know what the total teeth you can put on the car is? (spur + pinion).

Thanks for the help guys!

Yep, I was running a 54T Pinion on a 76T Spur with a 45mm tire at the beginning of the day. I have up to 60T Pinion's for smaller tires.

somewhere in these 2000+ pages, I think OD said about the smallest you could go would be a 71/72. any smaller and you would need run the smaller diff rings or i guess they call them the stealth diffs

abailey21

05-21-2009 08:46 AM

Yeah I haven't seen anyone making spurs smaller than like 71/72
