Hello all

I have a problem with bump steer. I have changed to short camber links in the front due to high grip (camber link pos. 4 instead of 3). It seems that i have now a lot more bump steer. Where do i have to add shims to avoid this?
I have added a shim on the C-Hub, it has limited the suspension travel but not much the bump steer.
With the long link, i had virtually no bump steer...

Any ideas?

The stock 72 tooth spur should work fine.

Default TC5

Treemagnet : you will also need to get a drill to the top slot of your motor mount just a very light skim so the motor screws lineup for a silver can.
72 spur is fine -if your track is about or bigger than 2 tennis courts run about 4.1 with a few straights if its tight hairpins etc 4.2 -4.3
If you have a motor cooler use it.
Oil the bushings everytime you run the motor.



Good luck

Shim on the c hub like caster block or the steering knuckle?

If you are having bump steer issues, you need to add spacers under the ball stud on the steering knuckle. Usually this is more due to a change in caster.

The amount you can lift the chassis up past ride height before the wheels leave the ground is droop.

yes and no. if your running rubber tires where the tire size doesnt change, you can use the downstop gauge to meaure droop, because the downstop value will produce the same chassis travel for all rubber tires. If your running foams, you will want to measure the chassis travel above ride height in mm for droop, because the downstop value will be diffrent for diffrent sized tires. you can also use the foam method on rubber tires (i do this, more convienient to measure than taking the tires off and busting out the downstop gauge.)

Just in my opinion Lunsford Ti screws are the best...they do have a set for the TC5, but you have to order it directly from them...

for every 10 to 15 screws you save about 10 grams, it just depends on how many screws you have! but dont bother with titanium screws because with lipo coming in you will need to add 200 grams to your car! and if you still want to put some put them up high so you can add weight down low to give you better centre of gravity. and try to keep your weight in the middle, faster reactivity, and the rest ude to balance left to right. and prob get a lipo tray as it helps add wieght under the battery because you may run out of room to put weight every where else. hope this helps you. And if you dont have lipo go roar legal packs, gauranteed quality and safety!

Hi, I just orderd the TC5R-314.99 at highvelocityracing.com with 10% discount-til 9/30. Is that a good deal?

Can somebody please tell me what is a good pinion to start with on the stock tc5r-48 pitch 87T spur. I will be running a Mamba Max 7700 with Maxamps 2s 6000mah lipos on the tc5r.

Thanks!
