Suspension - the important ratios?

[3GE Components]

What does the MX5 upright measure in comparison to the Sierra upright? Unless they are exactly the same in dimension across the ball joints then the front geometry using "book" mounts probably won't work.

There's far more to suspension design than just making it fit the car. Apart from getting the camber & castor right there are a host of other factors in suspension design to consider, some of them quite critical. My advice would be to get yourself a good suspension book ( i can recomend a few) and read it thoroughly.

With Chris's new book he has spent a lot of time getting all these factors correct, so much so that we have had to make custom uprights for him to get exactly what he wants, as nothing was available off the shelf.

Kind regards
