Default Car pulls to one side last half of track

Here's the scenario:

'92 Civic DX hatch
.Quaife LSD in S4C tranny
.DSS stage 3 axles/hubs
.22" slicks - no idea on the brand until I look at her car again
.spacers - probably 19 to 25mm's worth, but I haven't measured yet

The car pulls hard enough to one side that it scares her into letting off the last half of the 1/4 mile.

She had the same slicks last year but without the Quaife, DSS stage 3's, and the spacers. We had to use the spacers because the drag rims with slicks on them don't clear GS-R front calipers.

The car doesn't do this on street tires because we ran the car on Azenis the same night and she had no complaints. It ran a 13 @ 115mph misfiring because the plugs were gapped to .036" instead of .026" (not my fault honestly). So that probably rules out the Quaife and the DSS stage 3's.

The spacers are probably what's screwing things up, but I'd maybe like to hear other possibilities or explanations.

No. Never considered it, but I'll check it.

It took me a while to distinguish between overall wheel size rollout and rollout in context with staging.

Q. What is the maximum difference in rollout?
A. The difference in rollout between the left and right slick should not measure more than ¾”. A difference in rollout can cause the vehicle to pull. Inflate the smaller slick to about one-inch larger than the desired rollout and let it sit for a short period of time. Do not exceed 35 PSI. Deflate the tire to the desired pressure and re-measure.
