Crash Bolt Part Number?

[Figo]

So is that means to order a set of lower bolt 901000394 to replace the upper bolt 901000371 ? So after changing, the two bolt will be the same?

Yes, both the top and bottom strut bolts will be the same.

Buy from subaru. I paid $7 for both of mine.

That said, at stock ride height, the car toes in approximately 1/32 on each side after installation. a quarter turn on the toe arm should adjust this back.

I actually just watched the video and thats cool. I think I am gonna ask the mechanist to adjust to most negative while doing four wheel alignment after chaging my lower springs.

so any 1 know what is the part no. for STI front stock camber bolt? I think it is a 16mm size. or the 16mm cannot fit into our 86/brz?

So noob question....

I've been looking at what I need to get the most out of lowering springs and it was suggested to me that I use camber bolts in the rear and aftermarket crash bolts in the front. However, whenever I try to scour the internet for "crash bolts" I get nothing that is at all related to bolting the struts to the car. I am beginning to think that these crash bolts are another term for something that is probably staring me in the face. Please excuse my ignorance! What exactly is a crash bolt and how would an aftermarket crashbolt be any different/better than oem? thanks in advance!

Crash bolt is the same thing as camber bolt. When you crash your car, they use crash bolts to fix your suspension alignment. Hence the name "crash" bolts.

There are no camber bolts available for the rear. It's only available for the front.

I probably mis-remembered then. Crash-bolts rear and camber-bolts up front? I am planning on lowering the car with eibach sportlines and would like to dial in a bit of camber to be able to do some more aggressive cornering, but not so much that tire wear in a straight line is negatively affected (I realize there is compromise at play here) and I prefer to stick with springs versus coilovers from a financial standpoint. I have tried multiple times to find other threads about this, but I think I fail at the internet sometimes lol

Oh and thanks!

Edit: Found these on Rallysport Direct, I am assuming this is what I am looking for in the rear?

There are no crash bolts or camber bolts for the rear. They're only available for the front.

Crash bolt generally refers to the OEM bolts. Camber bolts generally refers to the SPC bolts. Some people prefer the OEM ones, some prefer the SPC ones. I personally prefer using OEM bolts over aftermarket. Both types of bolts will yield about the -1.5 of camber at the front.

When you lower the car, the rear suspension will naturally gain negative camber. At stock height, you're probably at about -1 at the rear. Once you drop it about another inch, you're probably looking at -2. I would not worry about adjusting camber at the rear -2. That's not a lot of camber. Make sure you fix the front and rear toe though.

The front of the car will basically stay the same when you lower the car. That's why a lot of people will add crash/camber bolts at the front to "even" out the camber for the car.

Ok, got it. Thanks I was super confused and you've cleared that up for me!
