Cool...
I wanted more camber in the rear. The tech said he could not get it and keep the toe I wanted also. What did he mean? Or is that BS??? |
AP1 rear toe in preference varies widely probably due to modifications, other alignment settings, condition of bushings and most importantly driving style. My 2001 has always liked the stock 0.24 inch total toe in--from stock to race car. I really wanted to run less toe in but every time I lowered it the stability and lap times suffered and I like a mechanically loose rear end to rotate the car in lower speed corners (the wing helps keep the rear planted in high speed corners). What I'm trying to say is I'm very comfortable sliding the car around on track but my car and I like 0.24 inch of rear toe.
I highly recommend AP1 guys stick to the stock spec until they are good enough to tell the difference and have the ability to play with the settings (i.e. test). The AP1 is tail happy enough without randomly lowering the toe. |
Yeah, I hope I didn't bite off more than I can chew. That said I am really on the rock bottom of the OEM spec.

The OEM spec in decimal degrees (what your shop used) is 0.56 degrees total toe in with an acceptable rage of 0.37 to 0.75 degrees so you are outside the lower end of the spec. AP1 (2000 - 2003) OEM Rear Toe-In Specs Inches: Total Toe-In is 0.24 inch +/- .08 inch or the range of 0.16 - 0.32 inch The latest Shop Manual specifies 0.24" where the original Shop Manual specified 0.25" (0.58 decimal degrees) For each rear tire toe-in is 0.12 inch +/- 0.04 inch or the range of 0.08 to 0.16 inch Degrees-Minutes: Total Toe-in is 0º 33' or the range of 0º 22' to 0º 44' For each rear tire toe-in is 0º 17' or the range of 0º 11' to 0º 22' Decimal Degrees: Total Toe-In is 0.56º or the range of or 0.37º to 0.75º degrees For each rear tire toe-in is 0.28º or the range of 0.19º to 0.37º degrees Millimeters: Total Toe-In is 6mm +/- 2 or the range of 4 to 8mm For each rear tire toe-in is 3mm +/- 1 or the range of 2 to 4mm |
I am going by their spec. They list .16* per wheel or .32* total minimum rear toe. FWIW this was done at a Honda dealer.

Apex, if you get a chance ask the dealer the source of their rear ap1 toe in spec. If I missed a TSB change I'd like to correct my website.
After looking at all the specs it looks like your dealer used CR specs for your AP1: CR OEM Rear Toe-In Specs Inches: Total Toe-In is 0.22 inch +/- 0.08 inch or the range of 0.14 to 0.30 inch For each rear tire toe-in is 0.11 inch +/- 0.04 inch or the range of 0.07 to 0.15 inch Degrees-Minutes: Total Toe-in is 0º 31' or the range of 0º 20' to 0º 42' For each rear tire toe-in is 0º 15' or the range of 0º 10' to 0º 21' Decimal Degrees: Total Toe-In is 0.51º or the range of or 0.32º to 0.70º degrees For each rear tire toe-in is 0.26º or the range of 0.16º to 0.35º degrees Millimeters: Total Toe-In is 5.5mm +/- 2 or the range of 3.5 to 7.5mm For each rear tire toe-in is 2.8mm +/- 1 or the range of 1.8 to 3.8mm |

any experiences with rear toe out? I recently set my rear toe to .1 or .2 out. I think its a more aggressive autocross setup. More grip at slower speeds, on a track/high speeds. I think its going to be oversteery
put a little under 250 track miles on my car with the new alignment specs. I have no complaints. All in all, my fronts have done 6 drift events, 5 autocross events, and 350 track miles, aswell as 8,000 miles+ The rears have 4 autocross events, 350 track miles and 4,000 street miles. F -1.0 camber F 6.1 caster F -0.01 toe Cross camber/caster 0.0 R -2.1 camber R .10 toe Front Attachment 186028 Attachment 186029 Attachment 186030 Rear Attachment 186031 Attachment 186032 Attachment 186033 i like how the rears are wearing. the shoulders are my fault (oversteer) / a result of the positive toe / going in too hot. I think i'm going to increase the front camber to -1.5 to try and wear the insides a bit more. |

I've played with toe settings and I've found between .2-.3 degrees toe-in at each wheel is the ideal range(which is about where the factory service manual recommends), and the higher the static rear camber you run the more you want your toe to be towards the high side of the range. I've verified this by measuring tire temperatures and tire pressures with various settings. I have access to an alignment rack, and have done a lot of alignments to the car. Usually before and after an event and everywhere in between. After .3 degrees you quickly start getting diminishing returns, and after .35 you actually start negatively affecting handling.

switched my specs around. more neg camber in the back vs rear. went for .05 pos up front and -.2 in the rear. specs are for each corner. liking them much much more.

Same rear toe in? Only +0.10 inch total?
