Davin, I will trade you my nearly new T3 2012 in a second for the T4.

That being said, I have a T4 that I have ran often since mid November, so has another friend of mine. Neither of us have replaced a spur gear yet.

@ Joe, I do not have the wedge weight, and see you soon buddy!

OK, it's gotta have something to do with the way the chassis flex's or bulkheads if the motor's not moving. There may be some guys that aren't having problems but, obviously there are lots that are.

I'm half way through my build so I'm gonna find out for myself soon.

We need one of the team guys to weigh in here.

That is definitely the other way around. I would say there is some that are having the problem, most are not.

That must be why all the major parts houses are out of stock on the most popular size gears. I was able to find 1 on stock at Nexus. I would be willing to bet there are alot more people than you think having the problem. Not everyone who owns a T4 posts on here.

I hope to have the car built for Tuesday practice. I'll be running boosted 7.5 on indoor carpet, decent grip... good load on the chassis, should be a good spur gear test. I can run back to back with my mod T3/12.

My son Blake is one of the team drivers. Like I said he runs between 25-30 packs per week for month's. He has 2 T4's running one in 17.5 and one in mod with a 4.5. With the races we have traveled with Paul and the Hardmans to, I can honestly say I have not seen anybody having a spur gear stripping issue.
Daven, I would like to bring Blake up to Oshkosh for a club race and maybe we can look at your car?

I have to say I'm surprised we have not seen option parts right before Christmas. I'm waiting for a new motor mount as well. Design wise I can't stand the nut and it looks like they took a machining short cut. Call me nutty, but it looks like trouble. lol

My guess it has to do with club racers banging off the boards. Team guys don't have this issue so you won't get a realistic assessment from them. There's a diversity of skilled drivers out there and everyone should be able to driver the car without issues. Xray can solve this be releasing a more solid motor mount. It's been an option part, so what's the hold up?

You may have solved the issue by now, but have you check the nut area and see if it's bent in the 90% angle area. Take a square and see if it's tweaked or bent.

Sorry,not a good idea.This will cause tweek and uneven flex.I always set my motor high off the chassis to avoid the motor ever coming in contact with the chassis.Don't have spur gear problems with a 4.5 turn boosted motor

Been through 10 packs, haven't stripped a gear. Broke 4 rear belts so far though (dusty asphalt)

Thanks

I found the kit setting for belt tension way too tight and loosen my belt up 1-3 notches (depending on the motors I'm running). Maybe that helps.

BTW almost 100 packs run so far on one spur gear.

I need some help to try and improve my corner entry steering;

Ignore the missed apex's

I seemed to have to scrub more corner speed than some of the others.
In ultimate lap times I was around 0.5s off the very fastest laps (Ollie Jeffries, Elliot Harper etc) and the only thing I could see watching their cars was that they had plenty of steering despit not slowing quite so much for the corners.

There are a few here, me included that aren't team drivers and have had no problems with spur gears. If a design issue everyone should be having a somewhat similar experience. Just because one person posts a hundred times that the car is flawed doesn't make a problem widespread.
