Title: drag front springs for full size
Post by: HR427 on September 15, 2020, 08:04:30 AM
what is everyone using for front drag springs? I have a 64 and have thr rear monoleaf/caltrac setup. I just heard over the weekend that you need 5 inches of travel up front. Was even thinking of 6 cylinder springs from Eaton?

Moroso Trick springs is what I've been using for years.

IIRC, I use the 47160 items in ny Falcon, which runs around 1750 lbs on the front tires.

I use Moroso 47190 in my wagon.  I did cut 1 turn off them, which puts it on the bump stops which makes it pretty close to the ground for headers.

For the last 10+ yrs I thought this is what the car needed.  I spent a day in July doing some shock testing and found out otherwise.  I have since bought a new set of 47190's and will install them UNCUT to raise the car up 1-2" this winter.  I don't have time to do it before the last couple races this fall.  After my testing I had to put a new oil pan and radiator in the car.  :o

Granted I have ladder bars and the chassis likely responds differently then Caltracs?  Up to this point I knew my car liked(needed) 8" of front end travel, but once I finally did some testing and found out I was completely wrong I want to get the nose of the car off the ground.  At some point I would like to make it street legal-ish and take it to a local cruise in.

Thanks Battlestar. I will look at those springs. What kinda 60 foot times are you achieving? I'll be running a g101a with a 3.17 1st. I think you run a g5r, right?

Yes, my 5R is 3.21 first.

I run 1.43-1.45 for the most part, but have gone 1.40 on a really tight track.

Front.  It typically drops right before the 60ft lights.  I've bounced over it a time or two and that will show a really slow 60ft.  Not very common though.
