New OEM camber bolt for coilover install? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Clipdat · 11-07-2018, 12:47 AM

I'm getting ready to swap out my coilovers for a different brand, and I was just wondering if it was advisable to replace the two bolts that hold the coilover to the hub.

I wasn't sure if the threads on the originals can elongate over time, and was just thinking it might be a good idea to replace them with new OEM bolts since everything will be apart anyway.

For reference, these are the ones I'm referring to:

I have camber adjustment on my top hats, so I don't need actual camber bolts.

Any advice/insight would be appreciated as I'm not a suspension expert.

Not sure if necessary, but I did. I believe factory instructions note that you should. Relatively inexpensive so I just figured why not.

Which part#(s) did you order? It appears that the top is a different size than the bottom.

I can try and check my garage tomorrow to see if i still have the part#

online search found:
SU003-02805 upper bolt
SU003-02818 lower bolt
SU003-02889 nut

Imho replacement is not needed. After all, how often alignment on car is redone. I doubt for threads to be anywhere close to stripping. Also i'd probably get lobed cambolts instead of at least one of oem bolt pair. Eases alignment adjustment versus simply smaller diameter bolts, which is case if one reuses stock 14mm bolt in 16mm upper hole. Even if you have camberplates, imho in some cases it's simpler to adjust from knuckle side, simply because of location (if car is rised on alignment rig for example and working from below car, also toe adjustment is also near).
BTW, in 2nd pic upper bolt looks like it's cambolt, not OE "crash cambolt" relocated from lower to upper hole.

top hats are nice, but a PITA to adjust compared to a cam bolt. Im running my lower oem bolt in my coils top hole and a 14mm cam in the lower. My oem bolts threading still look "new".

For the coilovers on my own car, I used 2 of the lower 14mm bolt and maxed out my camber adjustment at the lower mount. My camber plates were left in the OEM position, though I'm only running -2.2 degrees camber at the moment.

I did this to keep a lower SAI and this is what I recommend for most people. Get as much camber as you can from the lower mount, and get any more you need from the camber plates (but make sure the tops are even).

I run -3.6 camber in front; with just the camber plates maxed out I was at -3.1 and needed aftermarket cam bolts to get to -3.6.

I ended up ordering the OEM hardware from Subaru.

Here are the Subaru part numbers for those interested:
Upper bolt: 901000371
Lower bolt: 901000394
Nuts: 902380008

I'm switching to KW V3 which have a slotted upper hole, so I should be able to get some camber at the knuckle even with the OEM bolts.

Thank you all for the replies.
