Needing setup information on 2010 mastersbilt by mars late model

Spins out on the gas

[Hoyt3383]

Spins out before you pick up gas, but tight in? Wheel spin, but 3wheeling? I can be no help here.

I pm'ed you

smh @ Mars.. it's not rocket science. What are the chances you'll ever buy anything from them now that they've been zero help? The info below took about 2 minutes to type.

Can't help with the 4-link locations - never had a Masters with 7 hole brackets. At full droop you want the left top link to be around 47 degrees. If you get too much upper left bar angle, the back of the car will want to jump out on restarts.

17.5" upper links, 15.5" lower links. Can lengthen both leftside links 2 turns and shorten RS links 2 turns to tighten the car some.

springs and bite # sounds normal.

3 3/4" LF ride height
3 5/8" RF ride height
7 1/2" RR ride height
8 1/2" - 9" LR ride height

54.5 - 55% LS
54.5 - 55% R
with driver

I forget the LR chain measurement.. I think at full droop you want to be about 12 5/8" to 12 3/4" from the top of the LR tube to the bottom of the LR frame rail.

As for what the car is doing now.. what length j-bar? Does it mount to the center of the bar on the frame side? If not, it should.. I think 21" long j-bar is needed for that.

[Hoyt3383]

21" jbar it center of the square tubing that the frame mount bolts to. 9 1/2 inch up measuring from the bottom of the chassis to center of the bolt. Bottom of the pinion ( about 2" below the center of the u joint

[MasterSbilt_Racer]

Way too much j bar. Go to 8.5 on chassis and more like 1/2" below pinion.

[MasterSbilt_Racer]

Get your bar angles so that RR upper is around 20 degrees. RR lower 0 to plus 3. LR upper 25 range and LR lower 7ish. I ran drop where axle to underside of frame rail was 13.5"

If you have 33"/35" rear, inside of torque arm plate to center of RR frame rail is 16".

[Hoyt3383]

Will do. Appreciate you

[Hoyt3383]

What should side to side be measuring from the 5th arm bracket to the center of the RR frame rail?

[Hoyt3383]

How much bite to start with?

[MasterSbilt_Racer]

I would leave your springs and scale numbers where they are for now.

[Hoyt3383]

Thanks. I'll keep you posted

And if it has S-7 spindles by chance, the front ride heights are then 3 1/2" on both sides. I have/had an '07 Mars Smackdown and learned that taking LR weight out (bite) had a much better effect on side bite (and overall traction off) than moving the J-Bar/adding angle. Don't be afraid to get down to 50-80# of bite. They also have a lot of RR trail built into the mounts (RR is about 3/4" farther back than the LR at ride height). So don't be afraid to move the LR way back (I ran LR links that were 1/2" longer than what it calls for. I heard Babb ran the LR 1" further back when he was in a MasterSbilt). By comparison, look at where the LR wheel is in relation to the wheel opening on some of these Rockets and Club 29 cars when they go out for the feature. You'd think something was broken on the rear suspension!

We never ran that heavy of fifth coil either, usually 275/300.

I never ran that light.

[MasterSbilt_Racer]

A 2010 Smackdown can come off the corner. Watch the 33 win the race.
