After completing my first event of the season (and blowing up the engine) I discovered the front  tires are making contact with the fender lip and pulling the edge of the fender down into the tires on hard transitions.

The car has Bilstines struts and is fitted with an unknown set of springs. The car is using 205/50/15 (888R) tires on an unknown (light weight and British made) set of wheel, and the car has a manual rack.

What would be a good kit to start with (raise front  a bit) on this car, it's a race car and will see some road course and hill climbs.

 

Thanks, Paul

Lots of unknowns there!

So I'd start with what you should look for. You want a single-piece body so you can get maximum travel, no goofy two-piece setups that "let you adjust preload". You want damping adjustability so you can fine-tune for very different conditions and probably different spring rates. And you'll want to roll your fenders or find out what your offset is :)

I'd go with Fox myself because I agree with the guy who spec'd them out :) But it depends on what your budget is. A lower budget option would be V-Maxx XXtreme, but on a competition car suspension is one of the best ways to spend money effectively.

I would not get those Bilsteins revalved, because 1) I've rarely been impressed with Bilsteins and 2) you're at the mercy of the guy who revalved them and they're not adjustable unless you stuff them full of dollar bills, in which case maybe you should have started with a different shock.

Keith, yor are correct on the unknowns as a used race car has many, this is more of a temporary repair hence I am looking for coil overs as they can be adjusted and changed up to a point. After I replace the engine and have the cage updated i should have more time/money to upgrade or change the suppension. 

 

Thanks, Paul B

If you already have the Bilsteins and it's a "temporary repair", maybe a diy coilover by adding adjustable sleeves and budget known rate (Summit Racing) springs?  Will let you adjust the height and keep tires out of the fenders.  Just put together a set on my do-it-all 92, with reasonable spring rates set ride height at stock-ish NA8 altitudes.

Raising the ride height won’t stop fender interference. There’s always a bump big enough. The only way to stop it is to limit travel, move the tire or move the thing it’s hitting. I don’t even know if this is a Miata - I’m assuming not - so it’s hard to get any more specific than that.

Get adjustable sleeves like Keith said. Raise car up to about 12”. If it still rubs, roll fenders or buy different wheels that actually fit.

For my NA8 with aftermarket bilsteins (can't remember if there's a clip with the difference to the OEM bilsteins) I bought Allstar Bilstein compatible ALL64162 (5" sleeve), ALL64180 and 7" long 2.5" diameter front springs (550 rate). Not sure if you want to do something different due to your unusual wheels. I have 15x9" wheels, but I've also rolled the fender, lowered.
