Quick question, didn't I read somewhere, here on the forum, where someone just added an extra leaf spring (from an Alpine) to the Tiger rear spring setup? making a stiffer ride? Thanks, Tim

I've heard that you remove the bottom leaf to make them softer for handling purposes, if I'm not mistaken.

I added a second, primary leaf from an Alpine, after disassembling the spring pack, de-arcing all the leafs on a fixture Tom Hall has (to lower ride height), then reassembling. Did it a long time ago, but I still run those leafs on my car with good results. I believe it was one of Tom's common mods "back in the day" :)

Ride height??

Thank you Mwood, for the info. What would you guess, the ride height would be, if you did not re-arch the springs and use them as they are? It seems as if my springs are soft, and at every bump, the cars travel, (downward) is so that it hits my mustang rear disk brake calipers setup. ( the return spring on the caliper) - although, not by much, but does hit the upper arch of the frame. I do have new Edelbrock shocks, all new spring bushing, etc.

What might you say? Please advise, Thanks, Tim

Not sure how to answer that one, to be honest. I've never measured either a stock Tiger or my car to see how much droop there is under static load, i.e. how much the leaf bends when you put the rear end's weight on it. I'd guess using stock springs with the extra leaf would raise the static ride height a smidge, maybe? It definitely would give more rate, but whether that solves your problem, I wouldn't guess.

Are there options to create clearance for the caliper to allow the suspension to move without hitting? I'd rather keep rear compliance than try to keep the rear out of its travel to solve this one, personally :)

I agree. He can make new caliper brackets that rotate the calipers further down so that they out of the path of travel.

My original post was just that I never heard of anyone wanting it stiffer in the rear of a Tiger.

I know the question was on adding another spring to the rear but a better choice IMHO is the get a set of rear leafs from Dale.

Stiffer springs and anti axel tramp all in one.

Yep, agree. If I didn't already have what I have on the car, that's what I'd do.

I have Dales springs in my car, they are good but don't ride as nicely as stock springs, they also won't stop axle tramp on a warm motor... Over 300 bhp and you can wind them.

In 1965 Doanne Spencer ran what we now call a torque leaf in addition to the normal spring pack in the HSC Tiger. It was common then to also add horizontal shock absorbers going forward from to the rear housing to help the springs dampen the spring wrap-up.

Koni had the torque shock setup offered for the tiger. Owain Lloyd might be able to post the pictures of the setup that came on his mkia.

Buck, I think I read hsc55 also used additional early alpine lever arms on the rear at some point?
