Put on the 3 racing chassis and found out that my rear end grip is gone. I'm running trf shocks with yellow springs. I think 40 weight oil. Mazda 6 shell. What's an easy way to put some grip back in the rear? Softer springs or oil or both? Sway bars? Please help me out. I had to drive the car like this and adjusted my driving style. I'm an aggressive driver but couldn't be or I'd flip around at the corners.

Anybody interested in a TA05 with many hopups? Check http://www.rctech.net/forum/showthread.php?t=143968
I'm selling it because I switch over to the EVO5. A MR, EVO5 and a TA05 is a little TOOO much..

It's 100% legal. I also have a NIP set of titanium screws for the TA05...

I dont have my ta05 yet, its being shipped but I have heard of this problem before when you convert to the lighter chassis.

Possible things to try are

1) lighter rear springs (but try to be 1 or 2 rates max in difference between the f+r rate or you will upset the balance of the car).

2) use a low G of G for your droop setting, this will help the car "sway" into the corners more than a standard kit setting. Conmbine this with good camber link points. the shorter they are the better.

3) more additive on rear tyres.

4) try putting some stick on weights at the back end of the chassis.

Sway bars are not my area of knowledge so I cant say if they will help or not, all I can say is that they will help the ta05 immensley on carpet from what i've been told so just experiment with them.

As with anything, moderation is the key word so dont go too extreme on any change and do one thing at a time to see if it helps

You may find after some changes that you have (or already have) too much steering, so watch out for it and change your expo if need be.

If someone got an editable PDF of the setting sheet, I got a setup that is not finished but working well. I have taken the swaybars off, up the oil rate, moved camber links and increased rear-toe.

the chassis has nothing to do with it.. try rebuilding your shocks and then put blue springs in the front and yellows in the back.. i would suggest getting a sway bar.. and try saucing it or if you have tire warmers.. put 2 droop in the front and 4 in the back.. then 2 or 3 deg camber in the front and .5 in the back.. i forgot my toe in's.. but thats my set up.. it helped me win.. i hope this helps..

Thanks for the help. I was going to rebuild the shocks also. Gonna put in a lighter shock oil while I'm at it.

A full spring rate chart has been listed on the thread somewhere a couple times.

But to save you the search time...

Over the kit chassis, you will need to increase the front damping, soften the rear spring, and it might even be worth increasing rear-toe too,

Just found out that my right rear shock was empty and had carpet fuzzies inside. I'm running the 3 hole dampers. I'm thinking of putting blue springs on the rear and keep the yellow in the front. I'll add a tiny bit of camber in the rear too.

Heavier springs in the rear rarely work out.. you'll be spinning out at every corner. In the end you should have all 4 corners with relatively the same rate or fronts slightly stiffer if it's high grip, that way all the tires have the same force on the carpet for traction when turning. This doesn't always mean the same springs since shock placement, pistons, oil, sway bars have their own effects.

Camber should be generally the same front and back as well, 1 to 1.5 degrees.

Josh, try the stock 05 springs on the front, and yellow on the rear, but no roll bars.

I've tried stiffer springs in the rear on several occasions and found it to be a very nice setup if the track fits it. And thats just on this car, on my older Corally cars, we always ran stiffer springs in back.

It all depends on driving style and track conditions.
