Adjustable camber arms...alignment time! More parts?

OptionZero

Sorry, i've never heard of any cutting required to do a simple alignment on the back of a Z, and any shop that tried to tell me cutting the subframe was needed would be a shop i never go back to.

Get the 3 appropriate SPL arms and alignment is essentially limitless.

I installed adjustable camber arms and I'm on Swifts. Adjusting camber often changes your toe. Stock toe bolts may not be able to adjust toe enough to get it back within spec. That is why these exist. To install them, you have to elongate the hole the bolt goes into. That is the "cutting the subframe" dude was referring to.

SPC/SPL Toe bolts require you to elongate the toe bolt hole in order to have more adjustments or bring it back to spec, they even come with a template. Not much of a hack job it just requires you to grind down a small amount of the edges. Brought my car to Auto Innovation here in the Bay Area which is a known reputable shop here and even they told me I had to elongate the subframe holes to install aftermarket toe bolts.

Yup. Same here. Not only did one of the best alignment shops in town, Jack's Auto Alignment and Brakes, tell me that I needed it, the legendary Vitaly at Pitstop (the ONLY place I'll take my cars...) told me I may need it to get it back into spec, too.

OptionZero is right, this is the cheap incorrect way of fixing your toe/camber. Ultimately you are reducing the reliability and also creating a situation where those eccentric bolts will start to loosen up quicker over time.

The SPC bolts are essentially the same type of eccentric bolts as stock, they now have more adjustments due to elongating the hole. Im not sure how that is reducing the reliability as the stock bolts are also prone to slip over time and will slip under "high performance driving" as well. If we are talking about a weekend track car or even a dedicated track car then I would agree this isnt the route you should take, but as a Daily, spirited driving and maybe a track day a year this setup is acceptable and is the route I see most 350z/370z/G37 owners take.
