@Grasschopper check your PM's

I know I definitely pushed like a dump truck running closed cell fronts last year. Open Cell was half a second faster a lap easily. I sent you all the details in the PM, including the super secret stuff we won't tell Wildcat :D

Unless someone very fast and very reliable has miraculously found them to work on your certain track, I wouldn't bother with them.

As for the open cell inserts in the front... A 3/4 rear is still prett much the racing standard. I rarely have closed cell in the fronts... Usually I'm running slicks if I do, CC in the front helps calm the steering.

Been using red Aka front inserts for months now.

I like better then open cell because they don't wear right out and change the tires performance.

Hey guys, I'm having an issue with a chassis mounting hole being stripped as posted here. I can even push the Avid ESC shelf stand in and out by hand. I need some advice on this issue.

Thanks!

Use 5-40 x 9/16 screws to mount shelf...

4-40 will be to small and feel stripped if used...

Where can I get 5-40 standoff to replace the ones that came with the shelf? The one on the other side snugged up just fine.

Edit: Also, I tried re-installing the original mounting screw (removed the shelf) and it will not seat either. According to Avid, it replaces the 5-40.

"Set has titanium machined 4mm tall standoffs with ¼" hex which replaces the 5-40 screw."

If the screw you took out wasnt tight and the Avid standoff isnt tight then it is more than likely the hole that is stripped. You can always not use the standoffs and just use a longer screw.

Thanks, do you care to explain how this will solve the issue? The screw mentioned in the manual is 5-40x7/16.

It solves the issue because its longer than original screw.... It'll be breaking fresh ground.

Add the shelf's extra 3/16, a little longer screw is needed thus the longer 9/16 ..

I use myself .....

The website above has what I have used and currently have in my chassis now. Same location as you mentioned.
The Heli-Coil is what you want. Get the insert tool as well.
It is a lot easier than replacing the chassis.
A longer screw didn't work for me either...

Well depends on what you're looking for. Rear axle has a non threaded section that is 3/16" (.1875"). The front and rear axles are 8-32 threaded, major dia of 8-32 thread is .1640", close fit for 8-32 thread is #18 drill .1695", free fit is #16 or .1770".

Do you guys race 2wd buggy in the Fort Mill area? I have relatives in the area and have thought about bringing a car with me when I go to see them but haven't bothered as the only track I found info on their website didn't make it clear they were still open and they didn't return my email.

The Grove in Rock Hill has a lot of racing. 2wd buggy is hit and miss. Only 2wd is really SCT. I was mainly asking as I'm trying to find some 12mm hex to put on my xray to widen the rear without having to run different offset tires. Pretty close to the 4mm axle on XRAY TC. I'm going to have to get a pair to try them. Thanks for the info.
