I tried to purchase a OS Giken limited slip from Flying Miata but they do not have any in stock and the manufacturer stated that they are all on a ship and will not be to the states in a while. Do any vendors on here have them in stock?
I also found this different brand of limited slip (KAAZ). Has anyone heard of them and are they any good as it is significantly cheaper. Thanks
I've had my Kaaz 1.5 way diff for about 3 years now (maybe longer, I don't remember) and I have been perfectly happy with it. I upgraded from an open diff, so the difference was night and day. Lockup under power is smooth and consistent, pre-load was a little tight at first, but loosened up after the first 200 miles or so. I've always run the prescribed Kaaz gear oil in it, expensive maybe, but it's worth it to me.
It was a little clunky before break-in, but that was normal. Now it's only a little clunky after the car sat for a while and I do tight turns. That goes away after 2 turns though.
I did get it significantly cheaper than the link in the first post. I think I got it from Kaaz directly and came to ~$800ish including shipping. They even offered to adjust preload before shipping without extra charge.
I've never driven an OSG equipped car, so can't tell the difference but I would buy the Kaaz again in a hearbeat.
As far as I can tell, we are the only Miata specific vendor that custom tunes, road races and wins with OS Giken (not just our customers winning). Our exclusive SuperMiata Hi-Power tune for boosted cars was developed with OS Giken Japan. We are not just a dealer but a Master Warehouse Distributor for OSG.
I have driven track prepped Miatas with Kaaz diffs. Apples to oranges.
As in it makes the car loose? My 99' came with one and I'm wondering if it's really worth all the money to switch to a Giken or if I can make it work by dialing it in a bit with different fluid/preload etc...
We had fresh vegan donuts at the party last night. Basically, instead of milk we used soymilk and instead of eggs, we used egg replacer. Really though, you don't need eggs at all. Just a little baking soda is fine.
I won't have the budget to swap out the KAAZ to a Giken for a while so I'm wondering if there's anything I can do with it to make it a bit better. I have no experience tuning diffs but I can tell this thing locks up HARD which I'm guessing is why the car is loose on corner exits?
Mine came with the car and it's super clunky which is why I just ordered some KAAZ fluid but I'm wondering if it's worth it to pull the dam thing while I'm swapping out the fluid to try and dial it in a bit.
I've also noticed that when I lift off the throttle it seems to make the car want to rotate quite a bit which is fine most of the time since I know it's coming but every so often it catches me out.
On the other hand, I have 2 PAX wins in a row right now so it's not all that bad but it feels like a good time to try and make it better.
I look at how badly everybody slams on the KAAZ plus how much faster the Giken was in GRM's test and can't help but wonder if I can do something to improve this thing.
