Custom, I race a shortened 84 Crown Vic. What are some of the things that I can do to the front suspension to make the geometry better, ie. bumpsteer, camber change, roll center. Or is the front suspension pretty good from the factory? What frame heights should I run in the front? You use this style of front clip on the modifieds you build, correct?

This car has the stock replacement ball joints and tie-rod ends on, so the front geometry is stock, other than lowered. If I remember correctly, the front ride heights are set up so the RF ball joint pivot is higher off the ground then the inner pivot points by about 3/4", and the LF is higher by about 1-1/2" to the inner pivot. Is this correct. This equals about a frame height of 6-7/8 RF and 6-1/8 LF with the 88-7/8 RF tire and a 88-1/4 LF tire.

I have not race this car yet this year, and will be out in a couple of weeks. The last time I races this car it was fast and consistant.

One car I built we changed the spindles to gm spindles to make the frontend work better.

Custom,

When you build a modified with the Crown Vic front end, do you use the stock front end components and chane the spindles to a GM casting, or do you leave everything stock, minus the tubular uppers of course. What lenth uppers do you use?
