Why would you want to do that ???????

Are the rear A blocks the lower or higher roll centre adjustment?

Less castor, less rear droop, less steering wheel movement.

All the suggested things were already done... I just couldn't list them all in the first post hehehheheheheheh

I wanted to do that because I fell the could be faster I didn't needed to control my turning so much in the first part of the turn... The car feels a lot twitchy in this part and I would prefer it not to...

Did you really Mean LESS caster or MORE caster?
'cause as far as I am concerned more caster would aid turning instability and reduce steering

Try the B-Ackerman, this should reduce the initial turn-in.

I got to run the prospec yesterday. The stock setup is pretty good. The only things I changed were the B ackerman, A rear block (lower roll center), and 2 deg of rear camber. Pretty much hooked up for our track, even though I was only suppose to be running-in my new engine as well as the chassis.

I've always read that the B would increase the initial turn in...

Try it for yourself and see what it does......reading won't fully make you understand the effect on your car on your track.....besides....it only takes 5 minutes to change, run it, then change back if you don't like it.....It can't hurt...

I understand that the A is the most aggressive, followed by the B, then the C is mildest on initial turn in.......

(gotta be honest....I haven't tried all 3 either....just heard that the A is the most agressive and went that way......NOW that my curiosity is peaked....I think I'll try the other 2....just for fun....)

More rear wing....or move it further back on the body....THIS WILL FOR SURE take some twitch out of the car...especially at high speeds...... ...also...you could try a milder "flat-nose" body....don't know what you've got now....but this can work also...and...if nobody mentioned it....you can widen the front track...also a FOR SURE fix...

Already did that... gave me good results...

5 mins for changing ackerman??? How do you do it? It took me 20mins the last time I did it!!!! Maybe the next time I should consider running softer rear springs and the B or even C ackerman and switch back to front 40shore tyres...

About the rear Roll center... I've had better results with the A-block... strange isn't it?

A blocks used for high tracktion tracks
Less body roll Less side ways bite
So the A blocks lower the roll centre

actually, I think that by having a lower roll center the car will roll more...

typically you raise your roll center to present the car from rolling.

however, in the case of this car,I guess that by raising the rear roll center, you are actually incresing overall roll. So you are correct, the lower the roll center the less roll...

is there an easy way to change the part of the rear susp, that is up in the car a ways, the one that is labeled A, B, C. the back plate is easy so is the servo saver one but do u have to gut the back of the car to get to that other piece?
