haha let me rephraze...i hav an 04 so 4.444, wnt more than the current 4.778 in 09 stock rx8... Im kinda new to all this but, ring and pinion size and LSD are different products? i hav seen lots of LSDs but ring and pinion/differentials are kinda rare

 

yes,

and mazdamart is going to be your best bet.

but i have to ask what you are trying to do?

beers

 

Well the main focus is to hav alot better lower end power..im tired of losing the 1/4 mile...and turbo isnt an option due to location

 

unsure of location comment, but a 5.33 is not going to fix the tq and hp..

but you have been given the location for the gears..

beers

 

haha little island of guam.. and i dnt wnt **** half assed by sum selfowned sweatshop LOL it does help a little rite?? i saw an RX8 online with 10/35???

 

The only shorter gear ratio is a 5.12 R&P sold through the Mazdaspeed Motorsports racer program.

Mazmart can probably provide you with it. Otherwise they have a gear ratio thread in their forum vendor area.

tired of losing in the 1/4? get another car.

high odds are that anything you might gain this way will be lost by altering of shift points.

and the turbo comment... even FI, this is not a car easily setup for the drag strip. to do so requires much more than just extra power, you need to look at the suspension and tranny also

the cheapeast way to do this is to get 2 16" rims for the rear tires. 16" is the smallest rim the rear can fit. put a 225/30/16 drag slick on it. this changes the effective gearing and will give you the same benefits.

this kills 2 birds with 1 stone.

1. better gearing for the track. its also reversible so you wont kill your already bad highway mileage.

2. drag slicks will greatly help with launches and should knock at least .2 seconds off your ET. and since you dont have that much hp, and slicks are REALLY sticky, you dont need much more than a 225 or a 245. remember that a 245/30 has a taller sidewall than a 225/30 so your gearing will be less. with a 225/30 you'll have your best gains.

 

Don't forget to stock up on spare transmissions ....
