Cheapest Crash bolts
 
Hey guys, I've been looking to get crash bolts installed (when I do my eibach pro-kit). After searching around a bit, I have found that the subaru crash bolt part number is 901000394 and the scion crash bolt part number is SU003-02818 Each of these is a 14mm x 60mm flange bolt, nothing really special. So is there any reason we can't use the cheapest alternative? such as these: http://www.hondapartscheap.com/oem-p.../90162-sr3-000

Not that there is a HUGE price difference, but it may save a few bucks. I'm sure the grade of the bolt should be looked into before purchasing. Does anyone know the grade/material for the subaru and scion bolts? Thread pitch? Does anyone know if this will create a warranty issue, provided something breaks in that area of the car, etc.?

Oh and feel free to call me cheap... I'm still in school :P

I simply haven't researched it yet, but does the crash bolt (The subie community used to call them camber bolts) have an eccentric shank?

Or is it simply that it's a slightly narrower shank to allow the knuckle to lean farther toward the strut (small bolt in a big hole)?

If that's the case, I'm sure any standard flange bolt of the same grade or better would function much the same without any concern for safety. However, even the OEM bolts are pretty cheap things in the grand scheme...

The crash bolts are 6 bucks a piece. Hold on a second. I ended up going whiteline camber bolts, but I can show you a pic of both side by side.

Here you go. The one that comes with the car is the unwrapped one ;)

If you're going to go the bolt route, I suggest sacrificing a night at the movies and get the Whiteline 16mm camber bolts.
I had the pro kit installed and tried the crash bolt and I could only get .5 negative camber with them.
I had the Whiteline 16mm bolts installed and I'm around -1.4

Sometimes cheap isn't the best route.

I'm looking to adjust my rear camber after dropping 1" and have read about multiple ways to do it.

Rear control arm - expensive

Whiteline Rear Upper Control Arm Bushing & Camber Correction Kit - not the easiest to do, but not that expensive.

Camber bolts - cheap - ok to use for the rear? Upper or lower bolt, or both?

Crash bolts -cheap - ok to use, or camber bolts always better?

I feel like I should avoid crash bolts for spirited driving and autox like avoiding spacers because of the compromise - do people feel the same?

The crash bolts won't work in the rear. They are just smaller bolts than stock which is okay in the front because you have another bolt helping to hold things in place and the bolt hole size where it goes through the strut is the same as stock.

Take a look at this thread, you can modify some H&R camber bolts to fit in the rear.

Yeah, unfortunately, you won't be able to use the stock ones for the rear. As far as running them, crash bolts are 100% fine to use in autocross. In fact, you won't have a choice if you run in stock class as the aftermarket camber bolts are not allowed.

Spacers, in my experience, are fine too as long as they are torqued correctly. I ran them on both my cobra's at different points with no issues. Just keep things torqued. I've always heard that it could lead to premature wheel bearing failure, but I never had an issue. Both of my cars had 90k+ miles on them. The car was hardly a garage queen and she got plenty of spirited drives on winding roads (mostly palomar mountain here in SoCal)

I personally have the whiteline bolts because they came with the springs I bought and I figured "why not?" I do have the crash bolts sitting here in the tool box as I had fully planned on going that rout. I'm going to give them to a buddy who does a lot of spirited driving.

Spacers, I'm not going to run either. Just an extra part and mostly a visual mod. I've personally decided to stay away from visual mods on this car for the most part. Couple small things to set the car apart, but nothing crazy. I'll run a spacer if I get wheels that need them. :thumbup: but in all honesty, I will most likely be sticking with the stock wheels, just running better tires.

Are the "crash bolts" for this car from Subaru not cammed? My Impreza had cam type camber bolts in the upper slots in front from the factory.

Thorpedo 06-12-2013 04:07 PM

They are not cammed. I just got mine from scion for ~5 bucks a piece. People don't get much camber out of them due to variance in installation. I will be using a LITTLE weight of the car to ensure maximum gain. Some people see as much as 1.5 degrees from crash bolts.

xwd 06-12-2013 04:52 PM

Mentioned by another user, if you put a piece of wood on the outside edge of the tire and lower the car onto it, it will force the whole spindle inward. Of course this works best if you have the car on an alignment rack type setup since the strut bolts are a little hard to access with the wheel on the car sitting on your driveway.
