Seeking the best suspension upgrade

Post by Jeff Richards on Mon Jun 08, 2015 10:35 pm

I need to go to an aftermarket upper A arm for wheel clearance during tight turns. I began to look through all the posts on the old web site and got overwhelmed with all the information and opinions. I'm hoping someone else has done the research and can tell me what the "hot" setup is. I'd like a recommendation for upper and lower A arms, springs and shocks (or coil overs).

I'm also going to need the numbers for a front end alignment.

Can someone help?

Thanks

Suspension

The alignment specs from the build manual for a conventional Mustang II front end is:

Left Right
Caster: +2 + 2 1/2
Camber + 1/2 + 1/4
Toe In: 1/32

Just have the alignment guy's use these numbers. If they try to enter a specific vehicle into their alignment computer the unit may not "see" the Healey.

There are a lot of suspension ideas about and I like many am attempting to find a better way. I read a very comprehensive book on building suspensions and have taken the first steps to attempt to find this mathematically. My Healey just went to a race shop to be weighed. By the end of the week I'll have the total weight, front/rear weight distribution and the weight at each corner. With this and some measurement's off my current set up I will be able to use formulas to determine spring rates, shock rates, suspension "natural frequency" and travel etc. Once I know what I need the challenge is then to find aftermarket parts to achieve this if possible.

Will post what I come up with.

I would also like to see your progress on this. I would much appreciate if you could post your calculations and method, as I have an acquaintance that offered to corner-weight my car for free, and I eventually want to go to coilovers. Smile

Will do. Once I calculate the ideal spring/shock set up for a daily sporty driver the challenge will be finding the parts that comply. My assumption is that I may find that in the coil over realm in so much as the shocks can be fully adjustable. The air spring/shock set up may work, one of our members has that installed in the rear and seemed happy with it. The rear may need to be modified to a 3-link with either a panhard or Watts linkage to improve compliance. Dun no yet but I will absolutely share what I find.
