thanx mason. i never ran the old school front end but i want to try it. is it much different in handling? also does the front end have any camber without the shims. thanx

Just ran my CRC 3.2R on asphalt for the first time after much time driveing 1/10 TOuring car. Ran the 1/12 with Novak 4.5R(that's what I'm used to), but folks here tell me its too much for 1/12 scale, and that I should be running Novak 5.5R at the most for these cars, and that even the pros drive 10x1 motors...is this true? Anyone here tried driving 1/12 with Novak 4.5R and think its too much for these cars...I cannot tell since I dont know what they are supposed to feel like, since I have no experience driving 1/12 scale and cannot really judge at this point. It was a bit tough to handle went punching it down the straight...if you dont have it perfectly straight, you can be in trouble as it just slides/glides to the sides and becomes twitchy. After working on set ups, had to turn down D/R to about 70%, amongst other things on the radio. BUt overall, it was driving pretty well, at least I think so, but nothing like what I saw on orion website on those worlds racing videos...talk about geting dialed, and fast...I'd like to get close to that...running rear CRC pro cut pink and front purples.

some guys think its stiffer and were running it on carpet over the new style. that went away with the introduction of the brace.

you need to understand though that when you shim, you are changing ride height a little bit as well.

Most people just cut up a piece of header card and slide it under the outside of the arm. It doesn't take much to make a big change so you want something thin (around .008")

anyone ran an L4 with damper tubes rather than the kit disc setup?

how did it fair?

I'll tell you later on tonight as we have 6 RC12L4 which have been converted to the damper tubes that will be running tonight for the first time. I'll keep you posted.

xtrememadness:
I believe that the "old skool" front suspension has 1.5 or 2 degrees of camber and 2 degrees of castor already molded in. That is why it is hard to machine the front arms down to use smaller tires (must trim the steering blocks).

When i ran the old skool front end on my Rev3 and rev 4 I had slivers of paper and card stock of every thickness. header cards, business cards, thick letter stock, thin paper. I was pretty obsessive about getting the camber, axle height and caster even side to side. Took hours some nights. Dead balls on axle height was the most important, followed by camber then caster-though none should be way out.

Also-there have been some companies that have milled the old school arms down to run smaller tires on the SM cars and to make the arms "bluepinted".

also-just FYI-these new D-style diff rings are the best I and others (chicky) have ever used. No sanding to eliminate runout. VERY flat rings from IRS.

The rings look nice, but is there enough support from the hubs? If the hub does not cover 100% of the ring, spanning the four lobes could cause four tight spots.

Why don't we just have bigger inside diameter rings? IRS, Niftech, Asc... listening?

Still, I like it.

NOpe-no tight spots on any that Paul has installed and none on mine. We used to sand them not to get a rough surface, but to get them flatter. not anymore.

does anyone know of an online shop that has stock on a qc2?

thanks

Brian... got the bearings and bumpers... look great, can't wait for next weekend... Big Chill here i come...

i am using them now and really like em.they are flatter than the stock rings.i grind my rings to be flat within .0002. i only had to take .003 per side to get them dead flat.they catch the hub really good.i was curious if they would eat the flat on the hub but they have not even left a mark.i wont run anything else anymore.they are not only lighter,they are pretty damn flat too.

thanx for all the info guys. i saw that the rev 4 comes with the old school suspension and thought there was a reason speedmerchant specs it over the new style. i guess i can just run it with the new style as i want to try a link car over my rugrat. ray do you know who makes the blueprinted arms? i still want to have the option. thanx.
