Everything that everyone has said about getting to know the car before getting frisky is spot on, Ray. SPF's are pretty good cars right out of the box, so to speak, but there are a few tender spots that need to be upgraded. One that has spanned generations of cars is the upper rear shock mounts. For doing such a good job throughout the rest of the car those shock mounts look particularly out of place.
Cobra Valley, who offers a variety of very nice upgrades, has a fix for the rear shock mounts. This is what it looks like.
The whole package can easily be installed on a Saturday morning with a pizza and a few beers. Here is a link to their site with much more info, click here =>
Cobra Valley Rear Shock Mounts. The upgrade is SPF chassis number specific so look for the package that matches up with your chassis number.
