I want to clarify you said run 4 to 5 degrees castor but if you get 6 degrees something is wrong with the car. I run stock settings of 10 degrees I was going to this weekend try that tire combo would you say change it to 5 degrees. I was experiencing the same thing but I it seemed like my car would square up going into the corner

Thanks Chris

13.5 - Blinky Blue rear and Team Purple front.
Mod - longer conversation

If you are running the tire combo above then set castor at 4-5 degrees and go up or down from there. If you get to 6 degrees of castor something is probably wrong with the car.
Hope this helps.

What's the difference/advantage of Blue rears over Yellow rears?

Hello Jaybee,


The Blue rear is a Magenta / Yellow mix with this compound and the green compound you get more consistent traction. Over the magenta and pink compounds.

Hope this helps
Mike

.
Steve was talking about total castor angle of the king pin not the reactive castor setting. Slapmaster makes a gauge and some guys also use a camber gauge to get it close.

with any car you should check the left to right angle and make sure they are even, I've seen many cars of all brands have the same shims on both sides and come to find out the left has 3 degrees and the right 7. You can tweak your car all you want, if its like that youll be spinning out in one direction and pushing or ok in the other.

Hey Jaybee,

Im not sure on that question, But the best two people to ask are.. Steve Dunn ( sdunnmcp) (ProOne RC) 1/12th tires. And Paul C (chicky03) They both will be able to better answer that question.

Hope this helps
Mike

Green and blue are the same rubber family, Green is just softer.

I figured the 13lb center springs i had on hand would be too stiff but i guess the car worked pretty well most of last night. It was not my home track with different traction than im used to and some jumps in the carpet but with the larger touring car shock and lightest available ae spring car ended up with lots of traction and very fast response. Twitchy but never kicking out the backside.

Whether this will work in mod is another story. Ill have to wait til jan4th to give it a test.

Mine is dialled! All kit components with Rick's set-up from the 2012 Worlds and it is faster than I can drive it. The current leader in our BRCA National 13.5 Stock Championship is running an out of the box car with silver side springs and handing us our arses on a plate!

Great car, what's not to like?!!

So I am just looking for some setup changes that I could try to see if it will help.
I made the rear a bit wider and it seem to help. I still have the slight push mid corner in slow section of track. Will switching from BSR green to BSR blue help free the car a bit?

I posted this a few post before you posted this.

I am running th Black fronts with green rear tires.
I will have to look at my caster. I thougth I had it set at the 10 deg. with the shims set with 3.25.
center spring blue 30wt
side springs sliver when traction increases with 15K in tubes and 1mm pod droop.
Front:
.20 springs with 100K lube and NO droop. Camber I think is like 1 deg.


This is a 17.5 blinky setup. The front has the max caster setting other than the smaller shim in the front and thicker shim in rear on upper arm.
I do have the front about 2mm wider (per side) with shims.
