Alignment: Street vs Track and transitioning between

[Mturn0688]

All,

I've been looking around for a set of alignment specs that people have had success on the street (spirited but without making a mess of the tires) and the track but they seem to be scattered about the site.

Specifically, I'm looking to see how those of you who daily their cars and do occasional track days have their cars set up. Do you compromise wear on the street for track performance or the other way around.

I bought the MPP upper control arms to dial camber in/out in the front between both street and track. However, I'm realizing the rear doesn't have the same process (no quick adjustment to correct toe/caster) so it seems like a compromise or a new alignment each time.

Current setup: MPP Sport Coilovers, MPP FUCA, MPP Rear Camber Arm, 18x9.5 w/ 265/40r18 Eagle Supercar 3's.

Autocross- SCCA EV-X Class vs. SS

Has anyone come across tracks banning EV and hybrid vehicles? I'm over in the DC region, and saw something about Summit Point (on FB so not sure if true lol) no longer allowing EV and hybrid vehicles. Last year, I believe the DC SCCA chapter mostly ran at Summit Point and FedEx Field...

In the end, it really matters how much you track, and how much you drive between. But also tire wear on the track without enough camber can cost you a whole set of tires in one day, so in some ways the street doesn't matter at all.

I run full camber daily. I am at around 15k on my current set and will soon have the tires swapped side-to-side so I can spread the wear out. Including F/R rotation, I expect to get a safe 30k out of the tires without getting below about 3-4mm tread.

I run 0 toe front and rear, which I suspect helps with wear. I tweak to 1-2mm rear toe-out for autocross days.

I used to adjust everything for each race day, but it got really tedious. Plus, my +22 wheels wouldn’t fit without a lot of daily camber.

Thanks for that gearchruncher. I missed that in there.

Lindenwood, what camber are you running f/r?

Based on the feedback, sounds like I will set it towards track and rotate tires as needed.

Whoops! ~3.3f and 2.5r, and it is still tight with my +22 offset and +5mm rotor hats!

When I was still daily driving mine I would switch back and forth between my street and track alignment settings. Track settings on the street will eat up my tires quick as I run between 4 and 4.5* of camber up front and 2 to 3 in the rear. For the street I run 1.5 all around.

How did you get 4.5 degrees in the front of a Model 3?
What process did you use to switch the rear between settings, given the camber/toe interaction?

 

[subieworx]

I have UP upper control arms in the front and run at a decently low ride height.

I own a performance shop in Ohio and build many race cars. I have an in house alignment system so switching alignment setups is pretty easy for me.

My car.

I have redwood arms and currently have 4 degrees dialed with some caster. I could probably get to 4.5. I actually plan on running 4 on the street to see how bad my tire wear gets.

Lol. TIC... ya, you may know a thing or two about setup.
