The C-Hub and Lower U-Brace would really only be desirable on high grip surfaces. On most surfaces short of blue or black groove, the car would more than likely feel better with the A-B towers on (and and a higher inner ball stud)

I run on a track that is a med to lower bite clay track,i run the c-hubs and shaved brace and my car is on rails,rear end is really planted,i have yet to run the a block on my car but when i get enough time at the track that will be my next thing

When u say block I'm assuming that you are speaking of ballast. It will aid in traction and steering funny as it sounds it acts like a pendilum aiding in rotation also

What brace are you shaving? How much are you taking off?

You shave the rear u-brace. Shave the raised area where the ballstud goes. Shave it flat with the rest of the brace.

AE big bore springs are dirt cheap!!

I am new to this hobby so excuse my ignorance if the answer is obvious. It seems like every part has an upgraded or aftermarket part that is lighter yet I look at everyones car at the track and there are lead weights all over it. AE even came out with the weight mentioned in the post above to mount at the rear axles for better traction. Why lighten you axle/hub carriers which aren't driven by your motor so you have to add weight to your chassis. Is seems like the lower weight would help stabilize your car verse a weight mounted higher up in the chassis.

I think I understand the whole thing is about making money and selling everyone something they think will make them drive faster. Unless you are horsepower limited and using everything your motor can do, lightening your car won't make it go faster...hold the throttle longer.

He is meaning the A hub tower

I sure did . The 10.5 will take done getting used to, I need to reprogram my Esc it felt weirdike not linear on throttle. Gonna tweak on it a bit. Hope to race sat or sun

its about locating the weight were you want it to be. if you can lighten everything that sits on the outside of the center line of the car and add the wheight to the center line of the car it will be more balanced and predictable.

Having a lightweight car is great. It affords you more flexibility in positioning additional weight around the car.

All tunes, tracks, drivers, etc. don't need the additional weight, but for those who use it, it's placement in the car is key. Up high can add more roll, which equates to more traction (look at the 22's tranny weights), and adding it down low aids primarily in weight transfer/balance.

The change from the A-Hub / Stock U-Brace to C-Hub / -2mm U-Brace is a small one. It is a small change to roll center / camber change that can be felt, but is not going to make the difference between being the fastest car on the track to the last car in the D-Main. It is a minimal change, done for feel, which helps calm the car down on real high bite.

Thanks matt.

I guess the quote goes, if it aint broke don't fix it? lol thanks for the info

U can probably set ur esc throttle response to expo so it is more forgiving, it won't b linear but it will help take away some of the initial punch
