4.10s or 4.30s

k3vin · January 18th, 2009, 07:31 PM

Im going get some new gears for my 1997 cobra and i just wanted to know what a good website is for purchasing some. I've been looking around but I would just like some input.

also, how bad are 4.30s on highway driving? I don't drive on the freeway on a regular basis but Im wondering if its a big issue.

k3vin · January 18th, 2009, 07:43 PM

is it possible to know before hand how much the speedometer would be thrown off if I got 4.30s?

99blkcobra · January 18th, 2009, 07:44 PM

yeap theirs a gear calculator

Assuming you want your speedomter to read correctly, you'll also need to replace the speedo cable gear on the tranny side of the cable; if you do a search you should find a chart for what color gear you need.

And +1 on the Ford Gears.

Do they speedometer recalibration gears for 4.30s? Because I didn't see them on the FR website.

i have 4.10s but was also heavily thinking of 4.30s. will our cars run outta gear in the 1/4 mile with 4.30s (sorry to steal your thread)

03MachMe · January 19th, 2009, 09:33 PM

i have 4.10s and LOVE THEM im sure 4.30s would be just fine too if you dont do alot of highway driving.

i have a 4.30 gear in the cobra I just bought. I dont really have anything to compare it to other than my BMW. I don't think the RPM's are too high on highway driving though.
