So I am currently trapping 117.xx @ 6900 rpm at the finish line with the 205/55/16 tires.
Calculations say if I change to 205/50/15, I would hit 108.5 @ 6900rpm. Slightly larger tire 225/50/15 I would hit a about 112.xx @ 6900 rpm.
So.....
Technically I get out of the hole a bit quicker, but will the fact I need to shift to 5th be benificial?
I am making about 400/400 power....

real question should be 23" or 24" slicks.

Preload + semi slicks still= broken axles with this hp on early wrx or legacy gt Axles.
I would stay with the taller tyre so you dont loose tyre length (not width). Shifting into 5th before the line would be a waste of time UNLESS you plan on more hp. You could just put some 4.4's in next time you do a gear or syncro. What are your 60fts?

Nobody cares what you think Eminem

2.0 cause of bad tires and early season slick track.
This tranny has done 1.75 60' times in the gutted wagon.

I take it its not a 20 min job like a civic.
How strong is the tranny/diff ?

Na its all easy to pull out. We havnt had a diff problem yet but have stripped the teeth off 5 third gears, killed heaps of syncro's on track days and blown a few other gears. I found that using a twin plate clutch hurts 3rd gear more. We broke 1 front and 1 rear axle on 1 launch, also broke about 3 more axles that day on semi slicks. This is with between 380 and 480whp on a 97 STI sedan.

Oooooh they hurt.
Mainly because I could not hook up. My 60's were never better than 2.0....
I had ONE chance to break 12.5, but because I have never shifted into 5th at the dragstrip, I missed 5th and ran 12.6 @ 102.
The rest of the runs I was hitting redline right before the damn traps so shifting was a waste. Redline = 112.35 using 205/55/15 tires for me.
I felt I had one Awesome run in me..... wow what a hookup in third! what pull!
Then I shifted back into 1st.... The ONLY time I have ever done this. >:( To top it off, I was against a new camero, it would have been SO FLIPPING awesome to stomp it with my best run ever... Instead I did a 16.6 @ 109....
So.... Back to the crappy 16"!

Its got potential if it ran 12.6 @102 and a 16.6@109. keep working on that 60ft and get some low 12's :noel:
