Wow I am shocked that you would even ask that questionmtbmr2 said:My first chassis had 87+ brakes: http://www.pbase.com/mtb_zack/image/98010326
The DRW's I have are 13# each. In 13x7 wheels you have two choices: cheap, 13# steelies, or $200/wheel light wheels.
I'm curious, why does the track width matter? Solo rules for Prepared Class don't regulate track width. (In SOLO the penalty for a wide car is time lost on course having to turn further in slaloms.
But I will bite
1) And the most important is to follow the rules
2) Have you seen this formula?
LWT = Wx"g"xH/"g"xT
Herb Adams (father of the Firebird) puts it this way
?As soon a a car starts to go around a corner, its vertical tire loading will change. Because of the cornering force, weight will be transferred from the inside tires to the outside tires. This change in loading is dependent on the cornering force (g), the car track width (T), the height of the center of gravity (H) and the overall weight of the car (W)"
(See the above formula above)
The lateral wt transfer formula is reduced to this formula if you factor 1 "g"
3) I want to road race my car also so it would help if I could buy one set of rims that is legal for both solo II and F/E production
So when I read the stock track is 56.7
Then I read in the rules for MR2 track is 60.3 (E and F production)
So that?s the reasons why I was asking
Ok Flame away
