It can mess with shift points, not fuel or spark. But sometimes messing with the shift points is to your advantage.

I just see slicks as being a waste of money for Rad right now. That'* money that would be better spent on actual power-adding mods.

I agree 100% with willwren, slicks at the point are not going to gain you much and just be added stress to your tranny.

Sorry, popatim. Didn't mean to make you seem green.

I believe that the smaller tires would make it seem to the vehicle as if it is able to accelerate at a far greater rate than it really does. Also, being a smaller wheel, it would give me a greater initial pull. Sure, I won't retain my top speed, but I got this idea from something I saw on TV.

Some guys took a motorcycle engine & transmission and put it on a golf cart axle. The golf cart wheels were smaller than the original bike wheels. This gave the engine more "breathing room." That'* the best way I can explain it. This was a junkyard build on a show that would group together people, make 2 teams, give them tools, metal scrap, and a junkyard, and make them build various single-purpose vehicles. The show I watched was for drag racers. The car with a motorcycle 3-cyl engine and smaller wheels beat an Olds V8 and wide tires. I figured I might combine these into one mean, green drag racing machine.

Rad, you really need to start watching something else on TV.

Slicks are something you do when you can't get traction at the track. It would be a waste of your time and money at this point. In addition, if you go too small, it can really mess with your shift points to the point that the car would actually run like crap at the track without a custom tune for the new ratio.

My 95 is expected to run nearly 2 seconds quicker than your 94 this summer. And I'm not even beginning to consider slicks for it.

What if I were not to get slicks, but still wider-than-stock tires and also a tad smaller? Great tip on saving money for other mods, but I'd like to leave this for consideration for later. I'm not that far away from investing too much too soon, anyway, so this may come before long.

Wider should be unnecessary for your car. I launched on stock 225'* for a long time before I upgraded. You need to learn how to launch the car, not change tires. Go with a stickier compound in the stock size.

Don't change the diameter either, unless you're willing to screw up your shift points and get worse gas mileage.

I actually am pretty confident with launching my car. I feel my reaction times are high because I waited for the green light and didn't stress out my torque converter. I figured I'd use wider tires to cut myself some slack in the launch.

Reaction times aren't figured into ET. So they didn't hurt you. Your launch hurt you, or your car is running like crap. What was your 60'?

What was the 60' time on your slip? If your launch was solely to blame for your time, well... you need to get the lead out of your shoe at the tree

My launch time was just under 2.4 seconds. Here:
