Seat time
Brake pads: Winmax W5 minimum.
Brake fluid: Project Mu G-Four 335 Fluid
Hoses: OE brake lines OK
Engine oil: 0w-20 Motul 300V
Oil cooler: Required. Jackson Racing Oil Cooler
Tires: 225/45/17 GT Radial SX2. Not the stickiest tire, but gives consistent performance, lasts long and great learning tire.
Wheels: The stock PP wheels are good. Enkei RPF1 has weird fitment issues on the PP. I use OZ Ultraleggera 17x8 and has good clearance.
Suspension: Camber bolts ok. Keep the stock sway bars. No need for spacers unless needed for brake/wheel clearance
Safety: HANS

I can theoretically get more front camber with two sets of the camber bolts because the physical diameter of the bolts are smaller, yes?

I got -1.3 on both sides from just replacing the bolt (no swapping anything around). Works OK after several track days, given the fact that the rest of the car is stock (slow, low traction). If you want more, you have to use adjustment plates.

I got -2.3 on both sides by using two pairs of camber bolts. SPC 81305 and 81280. So it can be done without plates.

Code reader is a good idea for any OBD2 car hitting the track.

Should be able to get -2 or more with two camber bolts, well worth trying to get imho.

My friend, who owns the local alignment shop that caters to SCCA, NASA, and FARA racers, advised me not to double up on eccentrics. If I remember correctly, the instructions that came with the bolts from Whiteline said the same thing. There are lots of ways the YOU might choose to get more than -2.0 without plates, but I wouldn't...

OE camber bolts aren't eccentric.

I was attempting to point out that you could get ~-3° (assuming tire/wheel clearance) on just bolts using only one eccentric. I believe the usual answer is to get the bottom eccentric, and put the bottom bolt in the top.

YMMV, etc.

The camber makes a huge difference in tire wear though, not to mention front grip.

If you drill out/slot the OE bolt holes or use aftermarket struts with slotted/oversized holes maybe.

SSC konis have larger bolt holes than OE for extra camber.

Right you are, I always forget that.

Gotcha.

I appreciate the warning! I'm definitely going to be getting alignment checked more often to be safe. From the few people I've seen on here who have done it they haven't had any issues but that doesn't mean that it's not more likely. I'm definitely taking a chance on shear failure, for sure, though I believe it to be low risk. If it fails I'll come back and suffer the embarrassment as a cautionary tale...

This is really the first I've heard of it not being recommended, though. I looked through posts on the forum and didn't find anything against it, really. As I understood it the risks are pretty minimal. Are there any reports of failures or frequent slippage running two pairs of eccentric bolts? I understand why a shop would recommend against it, but is it a risk in reality?

Doubling up on eccentrics makes the system exponentially more susceptible to slipping from load. Remember, if *one* slips, there will be a cascading shock load that will most likely result in the other also slipping.
