Has anyone tired cutting every other tooth off the belts on this car. I know I tried that with the XXX4 I had and it worked great. This belt system seems much more free though in comparison. Just wondered if anyone has tried it and if there was any noticable benifets on the track.

Also my front belt runs right next to the pully wall/guides. My rear belt runs smack dead in the center of the pully. I tired shiming the front diff a bit to combinsate but the belt simply wants to ride on the guildes. With the XXX4/XXXS adjusting the how the belt rode was pretty easy to do with shimming the bearings with layers of glue. This car there doesn't seem to be a good way to make that adjustment. Maybe I'm overlooking something. Any suggestions?

For me the Numan set-up gave up no steering over the kit set-up. It settled the car down and allowed for me to make more of the fast lap times that I could hit with the kit set-up. If you put the Numan on it and you need more center out steering then run the 6 deg. blocks. If then you need more turn in go from the .100 shims to .80 under the front roll center blocks. Try that and you should be very close. Good Luck

Thanks for the info Brant!! I'll be sure and try those things out after I get my brackets in the mail. I really hope they come in tomorrow

I have kind of a stupid ?
We are running a huge Oval trophy race this weekend and I ran it Sat on the Oval which has a 205' drive line with 85' straights
The car ran great I did 5.6 sec laps but after we where done for the day I looked at the car and it has a lot of black on the left of the chassis
I know this is from rubbing the carpet My ? is can I just lower the shock collars and compress the srping more to help it
What will that do to the rest of the car for handling

Thanks

You guys are running a right handed oval? If it's scrubbing the chassis I would go with stiffer springs or even swaybars to try to take some of the roll out of the chassis.

Someone asked Matt Francis that exact question this weekend and his answer was that the different location had to do with the gyro effect of the motor. Having the motor in the forward section of the car would tend to make the car push, while having it mounted in the rear would promote oversteer.

weliin-I dont think anyone is cutting teeth on the belts. For sure I wouldnt cut any teeth on the grey belt. If you did the white belt-unlike on the Xray 04's or the XXXS's-I dont think youd feel a difference as drivetrain efficiency appears to be excellent already.

That's what I was leaning towards but was just wondering if anyone tired it. I've never had a belt car run this efficently.

I believe J Filipow was running cut belts with no problems mainly in 19 turn, dont know of anyone doing it for mod, but I dont think it would be any problem.

Do you guy's remember Isaid I had a rather large tweak when I built my new JRX-S !!!!!!!!!!! well
My car was great on rug, well it was until I decided to re-build it that is, you see, When I first built it there was a massive tweak in the car when I first built it! the left rear shock collar was wound down at least 3mm more than the right rear shock, and the front right shock was wound down 2mm more than the left front so as to balance it out on the tweak station (frustrating or what ) so ran it like that for the first meeting, and was built to stock. The back end was real lose, so I put some 1 degrees rear hub carriers on tuned over the rear wishbone retainer, and front rear wishbone retainers, so as to lower the centre of gravity at the rear and reduced the rear droop from 4 to 3mm and was bang on the money. Then I decided to re-build it so as to get rid of the tweak (not that I was in a hurry when I first built it as im not like that with my builds) I stripped it right back and re-built it checking on a flat plate as I mounted each individual part, but low and behold, come to checking the car on the tweak station, it had the same bloody tweak, I could not believe it. So i took it with me Friday to our club night and showed one of the guys that has been racing for arns, and sussed it in 2 minutes, the rear bulk head set are of different heights by 1.5mm and same with the fronts GGRRRRRRRRRRRRRRR!!!!!!!!!! Anyone else come across this? im gutted now i have to mess about shimming the bulk heads to equal hieghts
