Hello guys, please delete if this topic is in the wrong spot.

I am looking for some advice on chassis setup. My main question is, when I block the car to the recommended setup blocks I am running into the issue of very low ride heights. For example my RR height will be around 13.5” to the center of the torsion bar, with the LR around 11 1/4” and the torsion arm almost flat. Measurements are without me in the car, and with around 15 gallons of fuel in the tank.

21 Triple X Chassis
305 engine
3 1/2” RF block
4” RR block
-1” less on the left side blocks for raised rail
Around 12” stagger and RR spaced out 17-18”


In order to get to the proper ride heights do you go with shorter block heights to achieve the suggested ride heights, or do you evenly crank weight into the stops to raise the height?

Any information and advice is much appreciated!

You can do it either way.

You know your bars are good?

My question also, sounds like it might be where to start

Just for g and g with your setup blocks in all around, just in the rear,turn the screws a quarter turn in until you get the weight off the blocks and then see if the frame rails are close to what the builder recommends, I can do it in my head, but not seeing it makes it difficult

What do you call the proper ride hiegth? It’s been years since I measured one but those numbers don’t sound terribly far off and depending on where you’re gonna run they may be good

Let's try this again, setup blocks are for hot laps only, dry weight usually to get the car ballpark for out of the trailer practice or close after a winter of re assembly or from major work, a starting point, fuel is about 7 # per gallon, so you already have several pounds in the car, I'd say you are good to start
Just my opinion
