You’ll want max camber on the front so use two adj camber bolts. I was only able to get 1.2ish with one until someone at a track day told me he was using two. So I tried it and got 2.7. Cheapest way to get camber on the front (35 bucks + alignment).

SPC bolts are cheaper then $35 and exactly the same as the Whiteline.

Or just get SPC for the bottom and take the OEM bottom bolts and throw them in the top (since they are the same as the OEM crash bolts). You can get -2.5 or possibly more with just one set of eccentric.

I asked my shop to do exactly that after reading about it here and they couldn't get more than 1.2 on one side and 1.4 on the other side. With two SPC bolts per side they got to 2.x. Don't know why, but it seems that the SPC ones offer more adjustability than the OEM crash bolts...

Put another way, if you're going to pay $150 for an alignment, and you know for sure that two SPC bolts will get you in the mid 2s, why not just get it? I wish I found out about this sooner so I didn't have to go back and pay the same cost again for something that I could've gotten done right the first time around. FOr $18 bucks it seems like it's a worthwhile trade off. |

You ever experience any slipping with two eccentric bolts? How many alignments have you done since and was camber off compared to the prior alignment? I had heard its a risk but it's just been internet speculation basically so I'm curious. |

If I had a time machine I'd just buy the lower bolt and do what you suggest and save myself ~$20 (it wasn't well known that the 14mm for the lower hole was easily available, everybody listed the 16mm upper bolt as the only camber bolt that fit), but I think slipping is more likely to happen by doing that, the two cam bolts feel pretty solid as long as they're torqued down. edit: fwiw I got the car aligned in September, a week or two later I got rear ended, two weekends ago I put alignment tools on the car and read within 0.1 degrees of what the alignment shop set them at, so properly torqued a good cam bolt should be solid. That's through a car crash and several thousand miles of driving, a couple autox events sliding around. |

There was a lot of confusing info early on I recall with the 16mm vs. 14mm debate. But good to hear on the bolts holding. I figured if one bolt holds no reason two shouldn't, but I'm a suspension noob still so like to hear first hand experiences. And yeah, I didn't realize SPC bolts were that cheap now (I paid like $20-25 for mine IIRC and I thought that was about the cost of one set from Whiteline lol). |

Logically, I think you have to believe either that 1) SPC bolts hold or, 2) they do not hold. If they do not, it's not a question of 1 or 2 per side, they simply do not work. There's a scenario for 3, which is that the top does not hold but the bottom does hold, but having seen how they're installed I do not have a good reason to explain why that would be the case. |

Since you're already getting one set of SPC bolts and need an alignment, and they are effectively sunk costs, what do you need to believe for you to purchase a second set of SPC bolts vs. using the 14mm bolt from the factory? If your alignment cost is $150 then you need to believe that the 14mm would get you into the 2.x range at least 83% of the time (125/150). If you think the probability is lower than that, then you buy the second set of SPCs and understand that it's the right financial decision. Alternatively, you settle for whatever the shop can get from one set of SPC bolts. This does not take into account your time (just the cost of an alignment). Now I have no idea what the success ratio of getting 2.x camber with one set of SPCs + 14mm crash bolt and I mean that genuinely. I found out through experience that one was not enough, *for my car* You and others seem to have had better experience, and so the only thing that's clear is that there's no clear answer on the question. All I'm saying is that had I known that another $25 bucks would have *guaranteed* me camber in the 2.x range then I would have spent the money the first time, because my time (close to 3 hours b/t driving back and forth + actual alignment time + gas...) is more valuable than the $25 bucks and it's just not worth the hassle. So take it for what it's worth. Just putting my own experience out there as an option. |
