97 Cobra suspension and gears question

[97poizn]

I have a 1997 Cobra. I want to install 4:10 gears. Any suggestions? Is this a good gear? How about 4:56? I will probably install a Kenne Bell 2.1 later in the future.

Alos, I want to lower my car. When I had my 03 cobra, I installed H&R Super Sports with no isolators. Looked great! What is a good set up for my 97? Thanks for your help guys.

373s or 410s will work well with your car. 456 would be over kill. If you decide to get larger rims, stick with the 410s.

For springs I have always had Eibach.

3.55 or 3.73 will work great specially it is a DD, 4.10 will be to much for a dd , good luck!

No less than 4.30s if you will stay NA.

The blower will change some things but even then I'm going 4.10s.

4.10s in mine as a DD and it's fine. 4.10s for N/A and 3.73 for FI

4.10s in mine. And love it. Definitely end up shifting into 5th earlier, but no biggie. H&R Super Sports for me with isolators. Works great and looks good too.

I would rethink the Kenne Bell. No way to after cool with stock B heads. One member on here made his own custom after cooler, if you are real talented with phenolic you could do so also. So, either convert to C heads like your 03 had or go centri.

A nickels worth?

3.73s wouldn't be a bad consideration if you're definitely going with a Kenne Bell but if you end up staying n/a then they will be barely noticable over stock 3.27s. I've daily driven my cobra with 4.10s since 2012 and I have no regrets besides wishing I had gone with 4.30s. Also, H&R SuperSports without isos are also the most popular, lowest spring guys around here like to go with on sn95s that doesn't involve cutting coils.

This! You'll regret it if you don't and you race quite a bit!

4:10's in mine and I think they great ben at highway speeds the rpm's aren't too high.

Go 4.56. I have this gear. Very fast and is not over kill it 4v. After if you go supercharger just change gear

How long before you switch to FI? 4.30 on NA Cobra are a good choice. My car came with 3.73 and I'm not fond of them. Strange has gears on sale right now. http://www.strangeengineering.net/high-performance-street/ford-rear-end-components/gear-sets.html

Yep I've had my Cobra since 96 and have had 3.55's,3.73,4.30 and now 4.56 and these small displacement engines love to rev..

No to 4.10s.

Go with 4.30s for NA. Period.
Anyone that recommends a lower (numerically) gear either hasn't used 4.30s, or they just don't want the full potential out of the 96-98 4Vs.

You can go 4.56 as suggested too, but it's not as highway friendly.
I was regularly getting 21+ MPG in my car with 4.30s before swapping the gear when I went with a turbo. I run a 3.55 gear now, and really wish I went 3.73.
