Haynes shock specs

A colleague over here has built himself a Roadster chassis with a 318 BM motor. He's asked me what length shocks to run on it. Apparently the book states 13" rears and 9" fronts but I seem to remember seeing 14" as the 'new' rear shock?

Can any one help please.

Thanks in advance,

Mike

Yes, I also seem to remember mention of a longer rear shock. I think it improves drive quality on UK roads, without overly affecting performance.

I thought it was mentioned under the book amendments on the Haynes forum, but I've just checked and it's not.

Or it actually might have been Phil at Talon Motorsport, he regularly posts little bits of information on here that I have found invaluable during my build.

Hi Slimy. Thanks for that. Just jound it all here on the Haynes Forum and in a .pdf of post publication modshere.

The ideal choice now seems to be 14" front and rear.

In the book it states 13+1 inches. Basically a 13 inch with inch extension. Don't know what the difference is to a 14 inch one

Hi Ben. Apparently the car was originally designed with 13" shocks which will have a closed length of 9" more or less. By adding a 1" extension the closed length will become 10" so risking hitting the bumpstops too early in the suspesnsion movement.

A 14" will have a closed length of around 9.5" thus giving more wheel movement in compression than the 13+1".
