Can anyone give me information on XJ front springs. I have an XJ12C with a SBC - V8

I want a lowered stance - I've heard XJS springs will lower an XJ - Ive heard XJ6 springs are softer than the XJ12's and will lower a V8 converted XJ12

Right now my car looks like its sitting with the engine pulled - it needs to come down 3" or so.

I will have springs made if someone has a "blueprint" or specs for them.

I'd even airbag it.

Any ideas or information is appreciated.

 

Get 6 cyl springs and then add 1/4 to 3/8 spacer to drop the lower spring pocket. There is a 400 lbs diffrence between the v12 and the sbc. More if you have alaluminum heads so the v12 springs wont work. The sbc still weighs less than the 6cyl and thats why you need the spacers and longer bolts. Be careful when removing...v12 springs are no joke.
