Big healey coil springs

[Marvin Gruber]

We are converting my brothers 57 100/6 to front disc brakes using BJ8 axles so we can use the four pot Toyota brake caliphers. Not sure which coil spring to go back with. The 100/6 spring stands about an inch taller than the BJ8 spring and has about a half turn more coils. BUT the BJ8 springs are thicker, maybe 5/8" vs the 1/2" thk 100/6 spring. We want the car to stand a little taller. So comments please as to which spring to go back with?

It will sit higher with the BJ8 springs.

I put BJ8 springs on my BN1 and they set way too high so I removed them. Canadian retailer said they would be an upgrade for my car. Not so much.

The higher the from the heavier the steering and the higher that back the lighter it gets.ideally BJ8 springs cut to give the correct ride height would give better handling. I have a BJ7 with new front shocks and the front is underdamped and too soft at higher speeds IMO. It's pleasant to tour in though.

You mean professionally​ designed or hot rod chop or sawing off a section of the spring? I've read that one should not try to cut on springs, effects design or something?

When I swapped original 100-six front springs for the BJ-8 springs, the ride height remained the same, but the front end got nicely firmer. Newer shocks done at the same time surely helped.

We have BJ8 springs in our '56 100M and you need to add spacers to lower the ride height, the "hot" setup for a 100 racer is stiff in the front, and softer in the rear......

I put on Tom's lowering kit, just 1/2" but it makes a difference.
