Bolt size for the front lip?
 

The last shop I went to managed to lose most of the bolts for the clips that hold the front lip. Does anyone know the size of the bolts? Thanks in advance.

They are M6 threads with 10mm heads.

I would make them buy me new ones from Mazda.

hahaha while deserving, thats crule. just get some in any hardware store for like a dollar

Have you dropped the undertray lately? Those screws are big washer-head bolts. You need a big washer under each one, and if you're putting up the undertray it's a serious pain to deal with both a washer and bolt at each location. The OEM bolts are much easier to work with.

That's why I'd make the shop pay for them. Professional mechanics should NOT be losing parts, ever. That's as bad as someone putting work on my desk and me losing it.

You know, I guess I never thought of it like that before. On that note I would try and have the shop replace those bolts. But only out of principle... If you don't want to mess with it the size posted above is correct. If you want one to take with you just snag one from under the hood that help hold the front bumper on. Though I believe the ones you need are a bit longer.

Thanks. I just picked up the bolts at the hardware store. My R1 lip is now secured bolted down. :)

One of the reasons I do all my own work. Sloppy work like this is inexcusable - and letting them get away with it without complaint only makes things worse for everyone else. Any halfway decent mechanic would know that modern cars have literally hundreds of types of custom fasteners and losing fasteners should not be an option unless they plan to replace them with OEM units.

K so let me get this straight. I'm about to put my under tray back on as well BUT I don't have the bolts because I never had them to begin with.

M6 thread 10mm bolt with a washer did you say?
