The alcohol will clean the tire and the wintergreen will help them stick. Use this a couple of minutes before a race.
The trinity is much better of course and im sure theres a ton others. But it also costs 8 dollars vs the 1.50 or so for the large amount of wintergreen/alcohol. It gets you by....but if you want to be serious you might want to get the better stuff.
Remember though this will increase tire wear just like it were a stickier tire.

For rear traction issues, try going to a harder tire in front, say 40's in front, 37's in rear. Also try to disconnect the rear sway bar. Try running the car level, say 5mm front and rear, and you can also increase the rear toe in.
If it is higher speed corners that you have issues, move the rear spoiler to the rear most position. These are some quick tips...
You can also work on the droop settings, stopping the car from transferring weight to the front.

Bent elbow for the air filter? Use the Traxxas 2.5 air filter. It works good, and looks good too. CVEC has a nice aluminum air filter case, that uses the Traxxas air filter element and mounting.

Not the best picture, but if you look in the rear window, you can see the air filter. I have it facing to the rear of the car.

To increase rear traction for mid to exit cornering while on power stiffen the front sway bar or use harder front tires. Or you can soften or remove the rear sway bar or use softer rear tires. Increasing the rear toe in will give you more rear traction exiting the turn while on power.

I have a few question's. want to true up some tire's for racing.
1. how far should I cut the tire's down for racing? parking lot track and a little tight.
2.what setup station is best for the R40?
3.a good ride height to start with the track just a little bumby down the back straight.

Leave them box stock. Parking lots eat tires because they will probally put down traction compound.
Any setup station will probally do, and I would think either stock or 5.5on all sides would be a good starting setting.

But we will see.

My setup for my rear (which may be completely useless to you) is right now:
Running the graphite arms
Rear 2 degree Toe
3.5 left and 3 right rear camber
lower inner hole for link
2mm under rear upright
3mm front and 2mm rear for wheelbase
30,000 wt 4 gear rear diff
black swaybar with 1mm extra bar showing mounted to the OUTER holes (this is important)
innermost hole on shocktower
alloy body shocks with Kyosho Light blue Front springs
HPI 30 shore o-rings with greenslime
HPI 50 wt shock oil
HPI 50 shore Bladders
Derlin machined pistons with 3 x 0.9mm holes (I bored them .1mm from 0.8)
Hot Bodies hollow nitrided shock shafts which are also 1mm shorter.
3.5mm droop
4.5mm ride height
and I run nitro shoes, using 38 shore at 59mm generally

thanks bro...i've gone through and will try out as well and see how's the outcome! rapid boy gave me some suggestions as well from earlier post.there are a few things which i don't really understand like the rear sway bar, kyosho light blue front springs and hpi 30 shore o-rings and is the suggested droop and ride height for all round car?
thanks foe helping out!

well,I agree with one thing..the 4 gear diff made a big differnce in my car.....I tried it last year with 50,000....made the car have WAY to much steering.....so I took it out and put the 2 gear back in with 30,000.....But I think the silicone heats up,and the cars handling traits change....So the other night I put the 4 gear back in..but with a light coating in 50,000...NOT filled....just enough to give some lubing properties...the car ran perfect...and never changed the whole night....
