Manta A Springs

[doveyte2800]

Hi there,

Can anyone please tell me the free length and poundage rate of both front and rear standard springs for a Manta A.

Thanks

i'm actually also quite curious... would be interesting to see what other springs could be retrofitted onto it...

According to the factory manual the rates are :

Front : No load, 14.8 inch (376mm)

Loaded to 8 inch = 950 lbs

Wire thickness 12.15mm

On another page (very old pages) it says:

No load 12.8 inch (325mm)

loaded to 7.6 inch = 682 lbs (Im assuming these are the rears)

HTH

Front 14.8 to 8 inch = 6.8" 950lb/ 6.8 = 140 so maybe these are 140 lb/inch rating?

hi Tony,

Thanks for that, youve lost me a bit, but thanks.

Dont think your assumption on the rear springs is right as they are definately longer than 325mm .

Its a start so will keep digging

Yes its a bit vague in the book tbh. They quote unloaded (as in free length) then loaded to compress to a certain length 8" in this case and give the poundage once its compressed to 8"

Yes the rears are a wrong assumption as you say.

doveyte2800, whats your goal here? i can prob take some springs to work and get real world answers with used springs but i'm not sure how relevant they are for your case. Are you trying to get a specific ride height or poundage for an application?

Maybe its for the 2,8

hi TonyG,

I am trying to calculate lengths and poundage for the next rally car to replace the TE but i need a starting point hence the request for standard info. The ones we had for the TE are far to hard, thus long, to be fitted on a 2.0ltr.
