hi guys...sorry if my questions sound silly,

usually when i go to different tracks for racing i will always get early information regarding the track before i arrive. so that makes thing sort of easier to preset the car.
my question here , how do we determine whether d track is at what traction and grip level if we have no info's.

and what is the base setup u guys start with for
1. low traction
2. high traction

thanks

Try to find out what shores people are using there generally (say for a previous club race). That should give you a general indication of the traction but if its a temporary track made on a car park (and no sugar water is used) then you can expect it to be dirty/dusty and very little traction. I would sit out until some rubber is laid before going out to try my car.

If you have absolutely no reference, go to the track and sit out first while watching others testing their cars. Then check out the performance, ask what shores they're using ... you don't have to be the first one out on the track right?

Why dont the serpent diffs have belt guides on both sides??
My rear belt rides only half on the diff, new belt, tightness set at default, and the cams set the same both sides (double checked).
If I move the rear drive gear over so that the belt rides fully on the diff, then I have had the brake disc come uncoupled from the drive pins. If that doesnt happen, the belt falls off the diff.
Has anyone modded a diff with a guide on the other side?

Never had that problem with my 710 or 720, not unless your bulkheads are worn or bent, then you need to replace your rear bulkheads, that is the reason why your rear belt doesn't center on the diff.

how often do you guys replace tires? every race day, every so many laps, pit stop during the main?

what everyone's thoughts on jaco nitro shoes vs. grp tires? are the shore ratings basically the same?

Congrats on your performance. Way to go!!

i qualify on a new set and use fresh set for main....every race...

for me it depends on the "budget"
but at big races they always has tyres ready for each heats and finals. and like s10dude mention fresh pairs are better if u have the resources. But for budget racers like me, when i practice with new tyres i will keep them when they reach certain diameters that can be used for heats in future races. i keep them in air tight containers. this way i get to practice and already "trued" tyres

I never had this problem with the 710 or the 720. There is something not quite right in the assembly somewhere.

I'm a cheap-skate ... last weekend I used one set of tyres only for a club race. This was 4 x 5min heats and one 10 mins final so its only for a total of 30 mins racing time plus about another 10 mins total of warm up. I used GRP 37 fronts and 40 rears, started with 61mm and 62.5mm.

I've tried the JACO ones on Serpent rims courtesy of Julius a couple of years ago and it was well suited for the Heemstede track in Holland. I have not tried them since because I have some stock of GRPs and Speedmind. GRPs are great IMHO.

I can sometimes get through 2 club racedays and practice with a set of 35 Jacos. Most everyone here runs Jaco and most run 35's. Depends a lot on the smoothness of the surface you are running on.
Someone just brought in some GRP's never tried them, maybe I will try them out.

i also save all raceday/qualifying tires to practice with...

I tested a set of the old serpent springs this weekend (blue front, yellow rear) and was wondering what spring combination is equivalent to that setup w/ the new serpent springs ?
Thanks in advance

Try new blue fronts and new orange rears. Should feel similar.
