[Fot] Spitfire MKII FRONT Coil Springs

[A Page]

Peter, 

If your stock spring is indeed 150# and you think 180# might be good then a solution might be to cut 1 or more coils out of your stock spring - depending on how many active coils the stock spring has.

It's a linear change - i.e. If your stock spring has 8 total active coils and you cut one off you are increasing the spring rate by 1/8th. Or 150 divide by 8 = about 18 pounds. 150 + 18 = 168 - your new spring rate. You can cut a partial coil also and the simple math will tell you the rate.

After cutting the spring you can heat the last couple of inches on the freshly cut end and collapse the end and grind it flat to be finished like the uncut end; called "closed and ground". If you are careful not to heat beyond the inactive or flat part of the coil you will not damage the spring.

Perfectly legit way to lower a car.
