Considering getting new springs for my Squirt. What spring rates (tender and main) are you using on a 2 seat Squirt? Is it a short or extended 2 seat model? What engine do you have (just asking to take engine weight into consideration)? If you had to buy springs again would you buy the same rate or different? Thanks

 
Have a friend who has exact same setup and car and with 3.5a4. Only change is 091 instead of 2d. I texted him and waiting for reply.

OK, he got back to me.

Front upper 150 over 250 lower

Rear  upper 250 over 400 lower.

I don't have spring rates for you, but I have a sand limo squirt as well. Can you post a pic of yours?

What do you think is wrong with what you have?

Quick glance at your setup says your spring lengths are not right.  The preload nut is way to far down.  12" springs on a 14" shock.  Or both are way too light.

The springs are old and I am guessing have fatigued (maybe, maybe not). I revalved my shocks and would like to fine tune the whole suspension. Normally the preload collar is higher for a lower stance. Even at that level there is not much droop/sag. In a nutshell I would like the best size/weight springs for my setup and I'm willing to pay for them. 

If there are any more comments or suggestions please post them, I'm not a suspension pro and may not have noticed what is obvious to you (like the spring length).

It's highly unlikely your springs have enough fatigue to show noticeable collapse.  The springs on your buggy are made by the same company that probably made the springs on your wife's car.  Would you expect it to be sitting on the bump stops after 10 years?..  No.

Either the setup of your car changed,..was a 4cyl, not a 6..or whoever did that sweet, sweet paint job set it up wrong from the get go..

It did have a lighter engine in it before, possibly a mazda rotary. Joe Fab did not do the set up, it was done by an unknown fabricator. Thanks for the tips.

 
Maybe give Joe a call and ask him to point you in the right direction. He built a lot of those cars and can probably get you at a good base line setup. If you need his number I can PM it to you.

This.  I'm sure he'll sell them to you as well :biggrin:

 
Instead of guessing and asking others what the spring rate should be, why not actually calculate the spring weight based on the weight of your car. That video I thought was pretty spot on to follow and would be much more accurate. I’m sure you could get close based on similar setups but might as well dial it in based exactly for your car and weight and desired ride height.

I appreciate you posting the video. I also appreciate finding out what has worked for others.

I started by getting weight at the 4 corners. From there I talked to "Shock Talk" about cars intended uses and gave weights. This also gives front to rear and side to side percentages. I had shocks tuned and springs recommended for the cars purpose.  

 
Great video posted, but there’s one edit to the info: The spring rate calc is close, but the true formula is:

Upper Rate x Bottom Rate
——————————————
Upper Rate + Bottom Rate
