Cheers wayovermyhead,
I should have added further, that I'm also looking for something to eliminate rear tramp. As a previous grumpy pinto mk1 i had which i used King springs used to tramp all over the place (koni sports shock, but no lowering blocks, and only 185 road tyres).
So without having to resort to tramp rods I was looking to see if there was an easier fix. Which these springs seem to be.
As its a weekend/road rally/casual track car which ill probably use some decent tyres I'm looking for something a bit better than i had before. The Zetec I'm hoping to have around the 200hp mark on itb's.
I didn't realise these ones you were talking about are from King.
Thanks again for your help and the help from this thread. Lots of knowledgable people!
