Just ordered my 4.30's...some questions

[COBRA98]

What do I need to correct the speedo? I heard a 23 tooth will still be off. But I don't know if I want to spend $150 on a Speedo corrector b/c I will probably get a chip down the road.

I heard these 4.30 gears really open up the 4V. I really can't wait. With traction how much should my e.t improve?

When I installed 4.10's in my car I changed the speedo gear but it seemed to wear out fast. I pulled it out after a few thousand miles and all of the gears were worn down. I heard this was a problem with them. I installed the stock gear and changed to the Abbot speed compensator.

Abbot ERA... A few places sell them. I think I got a link somewhere around here... I'll be back if I find it.

Brothers Warehouse sells a compensator for under 100.00 It still performs the same function.
With traction is one thing, but how hard are you willing to push the car? It could be from 3 tenths to a second depending on your driving styles between your last pass (without gears) and your next pass (with gears)

Is the brothers compenstor as good as the Abbot?

I run my car up to 7000rpms. Could gears really gain me a full second in the quarter?

I think Brothers is selling the Speed CAL unit. It is a direct plug-in unit. It's $80.00 in their catalog. LOOK HERE FOR INFO

Going to that big of a gear can give you that much of a gain, but not always. Especially if the car never went it's best before you swapped the gear. Traction will be an issue I'm sure though.

I just got my 4.30's in yesterday i can't belive the difference. I love it. The RPM's go so quick i think im just going to have traction problems.

If you didn't, or whoever installed didn't do it...
remove the "dog-bone" mount from under the pumpkin for a weight savings. Since you swapped gears, it is now useless under there. It looks like a dog-bone and has 2 bolts in it.

Yep you're right. It is just there to reduce vibration. It is set for the stock gear, so changing the gear renders this thing useless. Good call.
