A reader in the comment stream from my post about Longacre Racing Products’ toe gauge asked about tools for setting the other two most commonly-referenced suspension characteristics: caster and camber. Caster is non-adjustable on the vast majority of vehicles. Unless you have a full-race car or some serious modifications, it’s never something you’ll need to worry about, since it’s built right into the suspension components. Camber adjustments aren’t exactly commonplace, but a few vehicles (like the famous Dodge Neon ACR) have factory-adjustable suspensions that allow camber tweaks, and you can buy aftermarket camber adjustment plates which permit slight shifts in a car’s suspension mounting points. For the amateur racer, more or less is generally all you need to know, but if you’re looking to repeat or record settings, you’ll need something like Longacre’s camber gauge.
The bad news is that Longacre’s version comes in at a hefty $131 from Summit Racing, with a flat magnetic adapter compatible with most wheels. Rebco makes an nearly identical version, different only in its measurement range, for a little less ($120). Either price is a little out of a reasonable range for most Toolmongers, but there’s also this from TomHoppe.com which covers rolling your own suspension setup rig with some relatively cheap parts.
