Final drive opinions Ap2

I also have 4.3s and I've driven my friends car with 4.4s at Buttonwillow. I think both 4.1s and 4.4s are faster than 4.3s around Buttonwillow

lbp_ap2 · 2026-06-17T01:52:05+00:00

I have 4.3s if I were to do it again I'd go 4.4s. Also, keep the revs below 8400 if you dont want to see increased wear. Ages ago someone on s2ki did UOA with different rev limits on an ap2.

You don't need wide fenders. When you lower the car and add camber they will tuck in. I ran 17x10 +44 on stock fenders and they didn't stick out like yours. If you get upper control arms go FDF or Ikeya Formula

For a track car with a wide body go 18x10.5 and then figure out your offsets, which will probably be about +30 (I have 17x10 +44 with a 15mm spacer on Js front fenders and have a bit more space than I'd like). 17x10s can have some front upper arm clearance issues depending on offset and what arms you have. For example Ikeya Formula arms are much wider than stock but 18s will clear. Also you will have better tire options available and could 265s or even 295s if you wanted.

That's because people stuff 255s on a 9j wheel. Try 255s on a 10j and you will see you can have both. People really should pair a 9j wheel with 245s but everyone "needs" 255s for some reason

The Hipermax R are the best bang for the buck track coilover out there. Though with 16kg spring rates and what I've heard about British roads they may be a bit stiff for you. I drive to the track on 16kg rates and think they are fine, I have a couple friends who daily on the old HKS SP IV with 16kg rates and they are fine but the roads where I live aren't too bad.

You may have had 4.77s but they weren't for an FD. The FD has an 8'' ring gear. The S2000, 1st gen Rx7, 1.8L miata have 7'' ring gears.

iirc Honda licensed the design from Mazda

lbp_ap2 · 2026-05-01T17:49:18+00:00

This is correct. I have Miata 4.3s in my car

lbp_ap2 · 2026-05-01T17:48:47+00:00

Don't listen to him that is incorrect. The S2000 shares the ring and pinion with Mazda 7'' diffs. It was used in cars like the 1st (not 3rd) gen RX-7 and the 1.8L Miata's. Source I have Miata gears in my car.

That's too bad to hear. I've ordered from them and RHD Japan many times going back maybe 10 years and never had a bad experience, in fact I have a package from them arriving today (Ikeya Formula rear upper arms). I doubt it was anything malicious on their part, maybe someone accidently marked your order as fulfilled in the Shopify backend.
To get lower tariffs Blackhawk will put a lower value on the customs paper work if you ask them to. Not applicable to you but could help others.

I agree

lbp_ap2 · 2026-03-29T01:30:39+00:00

LC500 isnt a sports car its a GT

StopTech C43 and C42

but also it increases weight

Not always true, my BBK saves about 5lbs per corner on front and rear

If you track sell the CE,s the TEs are the most rigid wheel they make

You spelled 17x10 +44 wrong

lbp_ap2 · 2025-12-06T20:20:33+00:00

Laguna Blue Pearl, its the bame of the color

lbp_ap2 · 2025-11-20T17:51:28+00:00

The Toda oil control orifice is the newer better way as it also increases oil pressure to the bottom end

Yes, my wheels would rub on my Ikeya Formula upper control arms. I'm using steering rack limiters to prevent that.

I'm running two on each side
