Crash Bolts!

Davis · 08-11-2009, 03:26 PM

Alrighty guys, I want to get -2.5 camber up front. What diameter crash bolts would I need? Also do I need to replace all 4 bolts up front with said size or just one on each side? Thanks!

Levi · 08-11-2009, 03:51 PM

use the smallest diameter crash bolt (12.8ish I believe) and only 1 per side. I was able to get exactly -2.5 front camber with this setup. Don't forget to torque those little puppies down (207 ft/lbs)

I also put 1 crash bolt smallest diameter on the rear but could only get -2 deg

Davis · 08-11-2009, 04:08 PM

Thanks Levi! One more question, does it matter if the crash bolt is installed in the top or bottom hole?

Levi · 08-11-2009, 04:10 PM

Put it in the top hole, there is less chance of slippage

Davis · 08-11-2009, 04:10 PM

Very good.

disagree, bottom hole, less leverage on that one vs the top one.

that being said I run two smalls up front at about -3.1*

Levi · 08-11-2009, 04:22 PM

aw sh*t, i searched and found ppl saying the top hole, but thinking about it the bottom hole does make more sense.

I'm leaving in mine in the top

kbrew8991 · 08-11-2009, 05:07 PM

if you torque the **** out of it, as in well beyond spec just like everyone else that doesn't get slip... it won't matter

with the bottom one you might see a miniscule improvement in tire/strut clearance and track width as well, again not enough to matter much if any

Davis · 08-11-2009, 05:34 PM

This thread turned out to be very helpful, Thanks guys!

Davis · 08-26-2009, 01:55 PM

So I did my alignment yesterday, I was only able to get -2 camber. All I did was loosen the knuckle bolts, replaced the bottom one with the 3dot crash bolt and pushed the strut in as far as I could as I tightened it to 200ftlbs. Was I supposed to loosen something else to get more negative camber?

kbrew8991 · 08-26-2009, 02:20 PM

you need the small bolts in both positions to approach -3

Davis · 08-26-2009, 02:25 PM

Ah, thanks Ken!

Haha gosh I feel stupid, you mentioned that a couple of posts above.

kbrew8991 · 08-27-2009, 02:34 PM

I think if you just wanted -2.5 you could do a small in one hole and a medium in the other, but minuswhale get two smalls - if that doesn't do the trick you've bent/broken something important

Davis · 08-27-2009, 10:09 PM

Lets hope not!

PCx188 · 12-29-2009, 07:44 AM

are crash bolts the same thing as a camber kit?

kbrew8991 · 12-29-2009, 11:15 AM

well, I guess in the very generic sense of both terms yes - you use either to change the camber angles on a car.

With MR2s, you're adjusting at the strut to hub joint. A camber kit like I've seen for some CRXs and the like move the upper control arm (a part we don't have, ugh) around to change the camber angle.

Hello guys,

I know this thread is a bit old, but I am wondering if Crash bolts are available for the MK1, and if so, what is the Toyota part number?

I ordered some Toyota bolts (90105-15006) but these are for the MK2 and do not fit the MK1.

I've been searching and searching and searching everywhere for a Toyota P/N for a MK1 Crash Bolt and I can't find it. Any help is much appreciated!

Thank you in advance,
BigMike

BigMike · 08-10-2010, 02:41 PM

Update on this...

I found a seller on eBay selling crash bolts for the MK1.

Here is his store: eBay My World - superautobac

Here is the auction I just ordered (link will break soon): COROLLA FX16 MR2 TERCEL CAMBER KIT 12MM: eBay Motors (item 220482529638 end time Aug-14-10 08:01:22 PDT)

They were $12 for a pair plus about $7 shipping. I'll update the thread with how they work, if they work lol

Regards,
BigMike

Hi,
Well, how do they work on Mk1 MR2?

I am running my Mk1 in ES. I think the crush bolts are legal and want to try it.

mach5mr2 · 10-15-2010, 02:14 PM

Those 3rd party eccentric bolts are not legal for stock classes, IIUC. The MKII crash bolts people use for stock classes are factory parts with smaller diameters. I think you are stuck with the stock parts for the MKI in ES.

I used those in the MKI and they were a complete PITA to install, and then to remove. They only got me from about -1.2 to -1.8, using them in conjunction with the stock camber adjusters. Since I am in CSP, I just went ahead and got the Ground Control front camber plates. Now I can get as much front camber as I need.
