Cutting Fiesta Coil Springs - advice ?

[Guest Combo]

Hello people.

 

Ive put together a fiesta for my son to race the "junior rod" formula at skegness and kings lynn in the new season.

 

Its a mk2/3 (i think) - 89F plate the rear springs are are mounted seperate to the rear strut (after 89 the rear suspension changed to coil over shockers) i think ..

 

I want to cut the coils to take the Rowing Boat feel out of the car but im not sure how many coils to cut off the front and rear.

 

Im guessing that with all the racers that use the forums i might get a bit of positive advice that'll save me maybe takin a coil at a time and spending time puttin together and takin apart again ..

 

cheers

Just gently heat one coil on each spring with some Oxy/Actylene gas....if you dont have gas, turn the power up on your mig welder right up, and just concentrate on ' welding' one part of the spring for a few seconds, it'll do the same trick.

mcrew , thats given me somthing to think about , a simple way to stiffen the bloody thing up.

 

Its 25 years since i raced bangers, MK1/2 Grannies and Triumph 2/2500's were 10 a penny then - the simple way then was to bang a couple of holes thro the shell fllor and wrap chains thro and around the (Rear) wishbones to pull the spring out.

I dont think todays scruitineers would stand too much of that approach

Hello yes you can cut the springs down but like said above if you want a easy solution then as long as the tank is out then heat them up and the weight of the car will lower the springs to the height you want.

 

Only thing you have to remeber is when you comprees a spring or cut the spring rate will also be more so it will stiffen as you make the spring smaller and if it is a rod then try to get the inside abit harder but shorter than the outside rear, dont no if you will get this if you just messing with standard springs.

 

Hope this helps in someway.

Cheers fellas for your input.

 

ill have a go with the "hot spanner" and see what gives with the springs.

 

It definately needs the bounce takin out of it.

cut a coil and a half out of the drivers side and a coil out of the passengers side then weld the springs into the cups and put a cable tie round the rubber bush and the spring, else they will come out when you jack the car up
