Rear spring lowering block

[dellyend1]

Hi All,

 

quick question - does a lowering block sit between the bottom leaf and second leaf of the spring or does it sit on the diff with the spring on top of it ? 
 

many thanks

Hi Jeremy,

It fits on the diff. and the spring sits on top.

yes come in 0.5, 0.75 and 1 inch thicknesses (= pretty much the change in ride height) with the last and possibly the middle one needing longer studs to still correctly clamp the spring...

And the last one needing you to live in a flat area of Norfolk, unless you enjoy the sound of your car bottoming out every time you hit a bump (in a Spitfire at least).

A 0.5" should fit fine, and under an unmodified cover with standard studs and nuts.
A 0.75" will need longer studs but if you trim them flush with the top of the nylocks once fitted will also fit under an unmodified cover - you'll just need a pair of 3/8UNF half nutsto be able to remove the studs next time around.
A 1" will need longer studs and some 'customization'/replacement of the cover.

I found the 1" too much, due to grounding and now happily run a 0.75" - but with hindsight would probably have been just as happy had I just gone for the 0.5".

Hello, have you any pics of your car with it lowered less than an inch please? I was thinking 1 inch but.....

Sorry for slow reply - time flies...

No pics handy but just had a quick measure and with a 3/4" lowering block the bottom edge of the rear wheel arch in line with the axle on my car sits 595mm from the floor.

Thanks for your reply, Ill need to measure once the tub is back on the chassis, but I will have already used a 1 inch block, see what it looks like 👍🏻😎
