I had a light conversation with Rob over the minimum 1380 weight requirement at last weeks CTS2 big race. I felt like it would be nice if the minimum was down to around 1360 as the lead that has to be put in these cars for 1380 is a bit excessive when you attend big races. I felt it would make life easier if the minimum would match closer to sedans 1350 because I tend to run the same chassis at different events but sometimes USGT and sometimes touring class. A 1360gr USGT minimum would make sets ups nearly the same for both classes but allow for heavier USGT bodies. Any way just imho.
What are your guys thoughts?

My ugly lead sled USGT car....

Use Tungsten weights.. You can get them them in 3/16" or 1/4" squares and they fit into tight quarters. I have used them for the past couple of years and they work great..

Goto Pinewood Derby Car Plans and High Performance Speed Supplies to get some

1. you need a better weight instead of those "old stlye" stick-on. "T" or the brass is cleaner and heavier without so many.

2. the USGT bodies are not much heavier, some are the same as most TC bodies. Some of the more detail bodies are heavier.

3. The weight is needed...I honestly thought it needed to stay at 1450. But 1380 works as well...will 20 more help more than hurt?...who knows. But USGT isnt TC, nor do "I" want it to look or feel like it.

this is just my opinion

Agree, also some of us that run older chassis's like the weight limit a little higher as it helps us as well. There is only so much you can save on a old tub chassis.

1380 would be ideal. I don't understand wanting to make it closer to a TC as well. If you wanted to run TC wouldn't you just run TC?

I personally do not care about the guys that want them to be the same for setup or what ever reasons. They need to be different.

How much does your TB03 weigh? Just curious.

I have to add a little (about 20gr) of lead to my TB03 to get to 1380 to run at TCS.

Right now I am at 1367g ( I thought it is currently 1350 for USGT )

That is with Stock Chassis, Alum prop shaft and alum input shafts, running a 2s 5300 lipo, ball diffs, Carbon Fiber Steering with Carbon Composite braces front and rear, Titanium turnbuckle set all aroun, and PF PFM10 body

Also this includes light weight CVD all around.

I removed the battery strap and 3D printed light weight battery hold downs.

Only thing I added was a 3D printed fan mount..

Yes I'm actually having a big brass weight machined up right now to go into that section. Just didn't arrive in time lol.

You say the weight is needed- how so? Can you elaborate?

Yes, we do not want USGT to turn into sedan but it is more similar than it is different

Ok thanks. Yes ours are very similar then. And see- even tub chassis has to add weight too lol

if the cars are heavy...1450 as before...even with the motors of the month, the extra 80 grams settle the speeds, as well as gave way to door to door....with lighter cars bumping is a bad thing....great motor or not 80 grams is 80 grams

I'd like to see USGT at 1400g. The 'reward' for running super-light chassis is figuring out where and how to add all that lead.

I understand technology advances, but let's leave that for the 'pros' running Touring Car and let us amateurs enjoy racing our older chassis in the scale classes like USGT and USVTA.

Just my honest opinion...

my AX car in tc trim pf r9 & jaco tires is 1352 balanced
exact same car in usgt trim (no added weight over tc) camaro body/gravity gt tires/wheels is 1380 balanced (same battery).
i ran the same car in usgt and 21.5tc @ snowbirds didnt change any setup ,(could have used more steering in usgt tho... )
which made it really nice to be able to run both classes at a large event since i only had 1 car to use

The minimum weight should be raised to at least 1400g.

Are you saying USGT is like Short Course truck racing? haha! Guess I haven't noticed a difference in that but I have noticed my tires, moving parts and bodies lasting longer since we dropped from 1450gr in GT and sedan classes.
