Hey guys i need to get my wheels aligned but the shop has the adjustment for toe in degrees and not mm

Any one know how to convert mm to degrees?

I've read up on some stuff but still not sure as some suggest using just the rim diameter but others suggest using the overall tyre diameter....i run 18"gtr wheels 235/40/18 up front and 265/35/18 rear

I plan on running 0* front and 2mm in on each side on the rear

Any links to calculators or such will be appriciated

Thanks

IIRC you can measure the distance between the front of both tyres and then the distance between the rear of both tyres. the differences is your Toe

in/out.

Ok guys this is the info. i aquired and this is what i'm going to use after lots of research...

Firstly you need to calculate the overall rim AND tyre diameter so using a 265/35/18

18" x 25.4 = 457.2mm

2(0.35 x 265) = 185.5mm

Total dia.> 457.2+185.5= 642.7mm

Next i want a toe of 2mm IN on either side so

Deg= 2(mm) x [ 115 / 642.7]

Deg= 0.357* for a toe in of 2mm per side

Toe IN is a positive value and toe OUT is a negative value

There are a couple of ways to calculate this but this method is the simpliest....well for me at least and i should note that you guys need to double check if your alignment shop reads toe in mm or degrees to make sure you are setting up your ride properly because it seems that all the newer machines measure in degrees and not mm.

    • Well, back in the day..... "race" fluids, which were essentially only really "high temp" fluids, used to absorb water more readily. So they really needed to be changed more often anyway. The coincidence of that being directly necessary along with it being what racers would do as a matter of course was just fine.
    • Does the high temp fluid degrade any different over time compared to normal one? That's one thing I've always been wondering. Because a track car is going to get the fluid flushed probably way more often than every two years and will see less kilometers driven. I would think the requirements are different. I'm running Motul RBF 600 in mine. Was recommended by my mechanic before a trackday and I've stuck with it since. Hasn't seen the track since but I've kept buying and using it for servicing anyway.
    • The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks.    OH, a quick side question - would you use brake fluid from an opened container even if the lid has been on? Eg, if you have a bottle that you opened last time you flushed, it's been tightly closed, is it still good? 
    • Nice, is there a post with the new 4" dyno curve?
