Suggested DD/Lapping Camber Settings
No flaming please. Constructive suggestions appreciated.
Some day soon my pile of aftermarket goodies will be installed with an alignment following. I’m sure the experienced alignment tech at Burning Rubber will have his thoughts but your’s are valued as well. DD about 20kl or 12 miles per year (no winter) and maybe 5 track days annually. My in-educated thoughts are -2.5 front and -1.5 rear. Mod’s will include; TRD lowering springs (~1” drop) Koni Sport Yellow (adjustable) 245 Conti ExtremeContact Front Camber bolts ( -1.75 max) Peddars Top mounts ( -.75 fixed) Rear Adjustable LCA Last edited by Muskoka800; 09-18-2019 at 09:53 AM. |

Get a pyrometer and use that to determine the ideal camber settings. Likely you'll want over -2* front.

Sean and another frien dof mine down here say the FRS/86 chassis loves camber.
But after talking with an old gumshoe of an alignment guy and my shop owner we decided on Neg 2.5 front and Neg 2 rear for dual sport autox/daily/track autox can eat up like neg 3 or more camber, but on bigger tracks with more speed you want a bigger contact patch. |

I guess his biggest question was optimum camber in relation to his DD mileage vs planned track day count. Pyrometer is good way to find optimum camber for one specific use, not so much what somewhat averaged optimum for mixed mileage would be.
Hmm, my choice would be .. while something like -2.3F/-1.8R would be somewhere in between DD/track setup, 5 trackdays .. have potential to wear most of full thread depth of tire set, so i'd probably would optimize more for track, with eg. -3F/-2.5R. |

I think -2.5F and -1.5R is a good starting point. You’re right though, the tech at Burning Rubber will let you know where you need to be.

I'm at -4.1 and -2.3, coming up on a year at those numbers.
I'd suggest -3 and -2 to start, 2.5/1.5 won't be bad, but you'll destroy the shoulders of the Contis before track day #5 if you're able to drive the car at 9/10ths consistently, the extra half a degree will help if you can get it. |

Depending on your skill level and how you drive you may end up doing more damage to the tires with lack of camber than daily driving with lots of camber. No matter what it's going to be a compromise that isn't optimal to either situation. I think you're pretty close with your guess, Imo, somewhere in the -2.5(if you're a less aggressive driver) to -3(if you're more aggressive) in the front and -2 ish in they back. Either way running zero toe will help your wear.

No AutoX in my plans.
DD and Lapping TMP. Sounds like 0 toe with -2.5 to -3 up front and -1.5 to -2 at the rear. I'll discuss those numbers with the alignment guru at Burning Rubber when that time comes, hopefully soon. Thank you all for your informed opinions. |

I've run a few alignment setups now and I found even with -2.2f/-1.7r I had noticeable outer shoulder wear on all 4 of my track tires (Hankook RS3) that was noticeable after the 1st season so it was clear that more camber was needed. I then went to -3f/-2.2r and I've been running that for 3 years now. Outer camber wear didn't get any worse on my track tires and there is no additional inner camber wear on my street tires so I think this is the sweet spot for me. Tire pyrometer also gave very even readings from left to right at 26psi hot front, 28psi hot rear with this setup, maybe 5-7c spread from left to right. I will note that both alignments were set with 0 toe. |

I haven't run the tires since last year and I can't remember what I ate for supper yesterday so... it's totally possible I'm remembering incorrectly. Thinking harder, those may have been cold pressures.
