The Schumacher shocks seem very smooth and I dont see the point in spending that kind of money on new shocks.

2. The car came with a 124 tooth spur. What is a good starting pinion to run for stock? I know I will need to fine tune the gearing for the track I am running, but I would just like to know a good starting point.

3.What a some good spares to have on hand? I am ordering a bunch of stuff from Schumacher and would like to know what brakes alot.

Any other info you guys have would be great. I am very impressed by the design of this car, I cant wait to get it on the track.
Thanks
Drew
1. The Schumacher shocks will work fine. The TRF ones are just easier for most to build and build consistently. Plus most companies springs will fit them easily without using preload spacers.

2. Don't know rollout but I'm sure if you go to www.gearchart.com you should be able to find a good rollout starting point.

3. Stock up on the usuals, front and rear arms, caster blocks, spare blades, etc... Maybe a set of hinge pins. As for upgrades, get yourself a P-Dub front bumper, a selection of springs, (Schumacher has a new pro spring kit out) and you should be good.

Depends on if you're running a spool or not in the front. With a spool running mod or 19 turn, I change the fronts every 3-4 runs. With a oneway or diff, they should be fine for a while. The rears I replace every couple of race days just to be sure. I keep a good stock of them at all times.

Thanks for the fast reply. My only other questions is, do you think that the BMI chassis is a worth while upgrade? I will be running the car only on carpet and I am interested in it. Is it worth getting or is the stock chassis fine?
Thanks

Also, where can I get a Pdub bumper?
Thanks again
Drew

Well...since we run in the 5.6-5.8 final drive range with the Reedy 19 on rubber (63mm) I would say try something around 5.2-5.3 final on 58mm foams. This would give you about the same roll out rubber to foam.

I had to go to Gearchart.com to figure this out...lol!

Start at 5.3 and gear up until you either slow down or the car starts to feel soft out of the corners then drop a tooth or two from that. You want to use the lowest gear ratio that gives you fast lap times. If you gear up and do not pick up speed you are just heating your motor up and draining your batts without going anywhere.

Absolutely. It's stiffer than the stock chassis and pulls everything in much closer to the centerline of the car. This will help it transition weight quicker and it helps keep it more balanced. If you're running on carpet, get the solid top deck for more rigidity. For asphalt, get the flex deck. The Teemu chassis is also very good for carpet. You can get a P-dub bumper by clicking on the link in my sig to go to his website and order one direct from PDub.

LOL, yep I had to go there to and had to "reverse calculate" my rollouts for stock, redline 19T's (orion based) and reedy quad 19T's ...found out I gotta use a smaller spur for the orion based 19T as I can't stuff a big enough pinion in my car to get the correct rollout with the existing spur!!

Hi all

Just preparing my Teemu chassis and was wondering how much material to take off the cell slots. On all my other TC I've only ever just beveled the edges. I'm running 3300s What do you all do?

Thanks
Tim

Just turning in a bit easier in the high-speed corners helps a lot.
Ok, then I assume it's not the tyres as they look very good, like they've only been used for a couple of laps.

Maybe it's my setup? - If the front tyres heat up before the rear then initially I would have good steering which would then turn to understeer as the rear tyres warmed up

Just take the sharp edge off the cell slot. Beveling is not necessary and will result in your cells hanging out below the chassis....not good...lol!

Thanks. We gotta start getting everything ready for the first carpet race in October.
