Default sumpin' i learned yesterday (rt question)

I learned I hate LED bulbs in the tree.....

but somewhere between the last yeller and green I need to leave, not on the last yellow or as it turns green....I'm going red by a LOT...taller frt tires? 24" on there now...
more pressure in the rears? (8.5 X 26 slicks)? other ideas?

not running stock (yet) running a stickshift series this year but maybe you guys can give me some direction...

Change the ratio of the clutch linkage for more travel at the pedal.

Put on the tallest tires that will fit first. The longer rollout will help ET's as well as slow RT's a bit. Then adjust the clutch linkage like Mark described.

I have to use 28" tires, I can't imagine getting a green light with 24". What kind of car is this that you can use 24" tires?

67 American...
I don't think I can get 28" in the frt, probably 26's

I've got the freeplay completely out, helped the shifting a lot ,was having issues (stone stock used st-10 3.42 1st gear)

measured 'em again today 24.5"....
would have to trim the fenders for much taller...or raise the ride height

Stock tires on my Firebird were 25.7", so I started with 26". I didn't notice it going any faster after the 28"s, just more green lights. After hearing how taller fronts show faster on time slips I decided to A-B-A test that. (I wear my junk out testing) I borrowed a set of 26" fronts. Back-to-back-to-back testing showed about nothing. I understand the therory, but calling it one hundredth of a second difference on my car (which repeats very well) would be a stretch.
