Anyone using the Moroso Front or Rear coil springs? If so, please post your data and any details you might have about them. My 72 Cutlass will sacrifice streetability for strip consistency.

I'm looking for a super loose front end, so let me know what you all are running and part numbers for both fronts and rears if you have them.

 

Isn't there anyone on this site using these springs or their equivalents in a bracket racing street car environment ???

 

I'd concentrate most on your reaction times and dial in strategy. The rear springs are a LOT less important in my opinion.

Tall and squishy is the key. Put some 50/50 shocks in the back and go man go.

How much horsepower are you running?

 

I'm probably looking at 275-290 hp at most. Just trying to turn 13's in 1/4, but I want the best setup and no borderline parts. I hate not knowing if I have the right stuff or wishing I should have done this instead type feeling.

Also my springs are the original factory rear & front springs and are sagging like you wouldn't believe, so they need to be replaced by next Wednesday Oct 26th to even pass my safety inspection.


I'm sure most of us have all been down that route before. I want to get it right the 1st time and not leave anything on the table. I would go with the Wiebe setup, but I want this particular car to run on the street occasionally without binding my suspension. I just don't think I need to overkill this Cutlass and I don't have much experience with street type cars that work on the strip.




Thanks

 

My car has a 4 speed so not everything I have done applies to an automatic car (which I assume you have). Get 6 cylinder front coils of about 250 lb/inch, and cut as needed to get the ride height you want.

 

I use Moroso Trick springs and adjustable shocks on the front of my '69 street/strip car. The car's back half of the frame has been replaced by a tube chassis with coil overs with adjustable ladder bars, so I can't help you there. 6.86 et at 103 mph. in the eighth mile.

 

i run low 13's with the stock springs kinda worn., stock shocks all the way around and i run convertable springs in the rear with air bags works great 60ft. times are all very close . i had the edelbrock anti hop bars for a while they worked good but when i took them off 60ft stayed the same i found that weird. they also bent my axle housing and an axle too much downward weight on a 40 year old axle housing

 

Hey guys, not trying to dig up an old post but I am contemplating the Moroso trick springs for my 1972 Cutlass Supreme...

My question is can I get away with these springs on the street? I will go have the car weighed and will buy the right spring rate for my specific car but I read that these springs are not for street use. Has anyone had any experience with these springs on the street? What was your experience? Good? Bad? Ugly?

 

You can use them, but I wouldn't get the lightest ones. See my post above. Also I found Moog, McQuay Norris, etc. OEM replacements to be higher quality and not to sag a bit over time like my Morosos did. I have several sets of front coils that I tried and if you want to try some, PM me. Only thing is, 68-72 originally had a square top and my 66 uses tangential.

 

I'm pretty sure I want to use the Moroso springs because I really want my car to launch hard at the track, I'm just a little worried about street driving with them. I'll have my car weighed and get the right spring rate for it but drivability is my concern. When you used the Moroso's did you have to trim them to fit?

 

Moroso springs won't guarantee a better launch than the proper Moogs, etc. Whether you have to trim them depends on free height vs. spring rate vs. weight of the front end vs. desired ride height. If you get light springs and drive on the street with a deep oil pan, you need shocks that are stiff on compression and a skid plate or other device to keep from destroying the oil pan sump.

 

Ed bigely was running a 260 lb spring with an iron headed BBC Chevelle and it sat low. I would definitely run the same with a SBO, which is quite a few lbs lighter than a BBC. I assume you're running a stock oil pan?
