Choosing the final drive and gearset that best works for you will depend on what type of driving/racing you do. The 4.6FD with Kaaz 3/4/5 gears will lower your top speed and works great for smaller tracks, rally-cross, autocross and tight canyon roads.

If you drive on longer tracks, highway/autobahn a lot then the 4.3FD with Kaaz 3/4/5 may work better.

If you could only do one of the two mods, gears or final drive, the final drive would come first. It makes a more noticeable improvement, is easier to install and less expensive.

Also, do not forget to add the Kaaz LSD to your budget, this will be the perfect time to install one.

Kaaz 3/4/5 gears:

Please,
4.6 install easier than 3 4 5 close?
Quicker acceleration with kaaz final or 3 4 5 set?
Maybe shortening 1st gear I suffer more wheel spin at launch?
Lsd suggested to improve traction?
I don't do autocross.
City drive, once a year highway, trackday at Magione Umbria Circuit
0.4 miles main straight.
From my data 6mph more with 4.6 than 3.4.5 close.
Not a difference.
Price alike.
Same work expense to me.
Still I don't understand which one allows more and quicker acceleration.
By your words it seems to be 4.6
then 3 4 5 only for long roads, finally best all together.
If I had 3 wheels I'd be barrow.. typical italian humour.
Seriously I don't like stock 4th length.
kaaz 3 4 5 closes all five gears.
Please tell me if 4.6 quicker than 3 4 5 close.
Or don't 3 4 5 make car quicker but only less speedy?
Thank u.
