"V Performance with there progressive rate fronts and single rate rears. Or do I use IPD springs. I have a set of Koni special D shocks and I already have installed a set of IPD sway bars.
Ideas?"
Last summer I called IPD to order springs and they only had ONE set of front sport springs in stock and were never going to order new ones.
I have v-performance 1 3/4" front progressive springs sitting in the trunk of my '72 142 :) They are very very impressive looking springs.
If you want to have stiff suspension, progressive rate springs are THE best choice for a road car. There is some initial give which absorbs some of the initial shock of the impact so you don't look like a ricer bouncing around the road and your back side will thank you too.
At any rate you have no choice since im positive IPD wont have front ones in stock for a 140 (and they arn't listed on the web page either). As for the rear springs the ones they sell for the 140 are infact for the 240 series car so they are in stock. You have to find a late (73-74) 140 or a 240 in order to switch to a different mounting style. I know my '72 won't take them without changing the mount.
Judging from the pictures on the V-performance site they are the same spring (just painted red) that IPD sells, but I haven't asked john if this is the case.
