i think i might have found some of my problems with driving. i decided to check my pinion angle. it was 2 degrees upwards!! what would that do to my car? anyways i reset it to 7 degrees down. what can i expect? also which side of the car needs to have a longer wheelbase for lead? i need to adjust this b/c the pinion angle change messed up my wheelbase. tomorrow will be a fun day of cutting and welding. yeeee haw. thanks ted.

If you do a search on pinion angle, You can see where it has been debated many times.......Most would agree that, provided that the angle is not extreme, it has no real effect on traction or bite......(in and of itself)

However, the method used to change it will......such as lengthen/shorten arms....they will also change the steer characteristics........

I'm guessing you lengthened the lowers?? Or drilled new holes in the Lower mounts??? The result would be less roll steer.....and not much of a change in bite.......

About the rear end lead.....If the left is forward it will promote oversteer...If the right is forward it will promote understeer.........Which do you want??

My advice......for a new car,new driver.....set it strait up......There are alot of adjustments to be made before one has to lead the rear..........

Good Luck,

Hey gould,
I see your name on here every now and then,
I had just had to write in and let you know
there is another gould out here. I am down
in houston. I went to your website, your
car looks real good. Keep in mind that you
could be getting some dynamic rear steer with
that car depending on ride heights and trailing arm angles. I agree with snowman that the pinion angle is not going to be a
huge difference maker, but every little bit
helps. We were rained out this weekend too.
Good luck to you next weekend. I will be
watching for some good gould results.

I have won some, but they were probably
accidents--or maybe the other drivers just
felt sorry for me and let me win. I have
a cousin William, uncle Ronny, uncle David, and father Bill who have probably won
more races than I have attended. So, there
are some Goulds out there. Houston does
suck for the cars I drive. Tracks keep
closing down, opening back up, changing the
rules, dropping sanctions--typical racing
**** i guess. Maybe I will have to move
to iowa and race with some new goulds--they
need any 3rd grade teachers up that way???

almost forgot...dynamic rear steer...
I run my ride heights a little higher in
the back than some of my compadres. My
lower two trailing arms run uphill towards
the front of the car. When i go into a
corner and the car rolls over to the right
(i do lots of stuff to help it roll over)
the right rear lower trailing arm flattens
out--which pushes the right rear wheel
back--also the left rear trailing arm is
gaining upward angle which pulls the left
rear tire forward. All this stuff going
on is my idea of dynamic rear steer. There
is not a whole lot you can do with a stock
metric rearend set up (not legally anyway)
by leading the left rear this way it helps
my car to turn a little better. Also, running
your lower arms uphill helps forward bite.
the down side is--some people don't like rear
steer, also if you lower your car down so
the lower trailing arms are level--then your
upper trailing arms are running downhill
towards the front of the car--which also
helps forward bite and eliminates most of
the dynamic rear steer. So, i guess its
a choose your poison kind of thing. of course
this is all my own opinion which probably
don't count for much anyway LOL
good luck to all the goulds out there and
everyone else too!! i hope all that ****
made some sense to someone

if he's got a race car, he might as well
be. William is my cousin, more like a
brother. One year older, we grew up together
pretty much. He runs full blown mods, I
am stuck down in the lowly world of limiteds.
William runs all over the oklahoma--texas
area. I think he has even ran some USMTS
shows and done pretty well. He won his
qualifier at the supernationals at boone
this past year and made the big show. He
is a racing fool. My uncle Ronny was on
the top ten most IMCA wins list for while
and he won the race of champions up in boone
a few years back. My family helps me
out tremendously. I am constantly trying
to become as fast as they are.

Gould..So how did you change the wheelbase? Change the lower arm mounts on the rear end?

Does anyone here box the rear contol arms on a metric chassis? If so, how did you keep them square? Leave them on the car?

i had to cut all the brackets loose and reset everything. upper and lower. make sure to measure everything while its on the ground. take note of that. then jack the car up and take measurement again. then you need to move the rearend as needed. put some good tacks on the brackets and set the car back down easily. then measure. if its where you want it then weld it up. if not break tacks loose and try again. hope that makes sense. it was worth the time....lol.
