Supra LE wheel lug bolts

[Skeeter]

Does anyone know the specs on the wheel lug bolts for the Supra? I could just take a bolt off and measure it, but the car is still over at the dealers for some detail type work, and a new battery replacement (the dealer buckled the seatbelts and left them that way, which let a parasitic drain on the battery) so I can't measure them myself. I have a set of M14X1.25X26mm titanium bolts that I think would fit, and would like to use, however I'm just not sure of the length of the OEM bolts.

Did you find out how long are the OEM bolts? I am also trying to know..

Haven't heard anything back from anyone yet. I am going to take one off my car and measure it. I'll let you know when I do

Hey I was wondering the same thing. Did you measure it?
Thanks

I measured the thread pitch the other day and they are definitely 1.25 but I didn't measure length or diameter (from other articles I've seen I believe they are M14 diameter though). If the length is important, I'll measure mine on Monday. 26mm sounds a bit too short to me though.

The lug studs are M14 X 1.25MM.. I don't know whether to measure from the bottom of the bolt to the bottom of the conical seat, or to the top of the seat. However, I believe they are 48mm long, M14X1.25X48.

Ah I took one out today to measure it for you but seems you've already done it

So it looks like the bolt measures 28mm. Anyone know how much clearance room there is behind the bolt when mounted. For example, if using a 50mm bolt would it hit behind the wheel?

Bolts are always resized (when you add/remove spacers, etc) to result in no-net-change of thread engagement, which suggests the depth is important.

Stick the stock lug bolt back in the tire (not on the car , obviously) and then measure how much of the bolt protrudes past the back of the wheel. This is the length of engagement in the hub/rotor.
