It seems like the tire is drifting a little more and not much steering or grip. Lap time also slower. FYI, I have kept setup same when swapping except with rides needs small changes to setup. Tires prepped and sauced with tire tweak. I also checked tire temps, all tires including Sorex and rides mounted with sweep wheel and sweep pink inserts about 50 Celsius after 6 min run. All tire wear is acceptable.
Thanks

Now, tires are open and we tried exp evo 30deg.We have tested at 10-15C so far. We just dont have front grip, the car pushes at all corners and at the first lap the car is drifting. Tires sauced with sweep x3 and tire warmers always. We have tried the aqua insert and the ls which produced a little bit more front grip but nothing special. We have been testing back to back with the 36r that seems to be always faster. Only advantage with the exps is their wear which is almost zero! What do we need to do to find grip? Maybe wait until the temp goes to 20+ C ?
We also need help!!!

Evo evo tire will work fine after their shiny surface faded.
For smoother asphalt, you will need to run them 3-4 runs until you have good traction.
For abrasive asphalt, from second run you will feel better traction.

1)If by FX2 you mean paragon, we cannot use it, as it is forbidden due to its smell. Can we find traction with sweep additives?

Try X2 only
or
Clean the tire with X1 then put X2.



2) So, we need to sand them before the first run, correct me if I am wrong.

Yes. it will help getting good traction from new tire.

3)Our track is not so smooth, but low-medium grip. We will have to run used tires on the race, tires that have been "broken in" during i.e Saturday practice?

One run tire is better for the track condition I think!

4) Temp is getting more and more hot here. On April 14th when its our first national race it wil be around 20-25 C. Can we be confident that this is their temp window and keep testing them until then? Or the standard r series could be quicker on the track? We need them to last 2-3 runs only as we are allowed to use 2 sets and the race format is 3 qualifying and 3 finals.

The only downside to the OGSPEC, the rims crack quick, but you could get different rims. Sweep should chime in about that. I too would like a OGSpec on a more durable rim.http://www.sweepracingusa.com/110-OG...ons_p_370.html
Not a bad deal for glued wheels tires

We discontinued the old white wheels (EXP-WAW), please try the new one with hole rimmed out little from both side if problems happens.
as far as we been reported, only the Awesomatix having an issue with Hex.

We will keep our ears open.

thanks

thats only for EXP-WAN (Natural stiff wheel), have you tried those wheels yet? spins true, stay true after crashes but one of our driver reported having a issue with Awesomematix hex, but that can be just him.

Thanks for the information.

However, after the run, I was able to put the thumb screw on just one or two threads, then push the thumb screw with my thumbs while pulling the wheel evenly from the edges, and they popped right off. I didn't ream the center hole, because I didn't get that suggestion until I had already put the tires on.

Malkiy runs an Awesomatix. I think he mentioned that Magnet Top (Jake D) had the same fitment issue. All 3 of us are in the same club (Seattle RC Racers) and probably got wheels from the same batch (Emerald City RC / Kody Knudson).
