The XB/XA rear hubs are garbage. I killed 5 in the first 8 events of owning the spindles. Tried Timken, Moog and a "no name" Brand)
Spend the extra couple bucks and get the MR2 front hubs. They have been in the spindles for 2 full seasons and are still going strong. Timken.
.
When I talked to Andrew about this, he let me know I wasn't the only one having these issues with the XB/XA stuff.

Hello all,
First off, I want to thank the moderators for giving me the opportunity to post on behalf of my retailer, Bill Wilner of Miataroadster.com. I would like to become a positive attribute to the forum by answering any questions in regards to my product line and also share any information regarding chassis, steering, and suspension dynamics.
I'm a little late to this post, but I have attached a link regarding information and precautions for the drop spindles-
https://drive.google.com/file/d/0B_l...5pd2k0ZWM/view
This link is constantly updated and provides accurate information to the Gen1 and now, Gen2 drop spindles. Many of the fitment hiccups of the Gen1 spindles have been dealt with after more then 2 years of testing all over the globe.
Before I get into "custom shocks", please remember that the NA/NB chassis have a .7/1 motion ratio front and rear. This means for every 1" the wheel actuates up and down, the shock moves .7". To compensate for the 1.5" drop in the spindle, the shock would need to be an extra 1.05" in length.
We offer 1" thick shock spacers that will compensate for the drop in the spindle while leaving the ride height roughly .07" lower then before the spindle and spacer install. This method does not change shock travel.
Some aftermarket shocks may have an interference issue with the spring perch and the rear axle shafts. A quick fix for a moderate level fabricator is to ditch the shock spacers in the rear and fabricate a pair of lower shock brackets with the mounting hole raised one inch. With a angle/cut off grinder, drill press, welder, and a little patience, one could make quick work of said brackets. The OEM brackets can be completely done away with, or the new brackets can extend off of the OEMs with the right design. All though I don't offer these brackets as a product, I am always happy to assist customers in the simple design of these brackets or even fabricate the brackets onto control arms shipped in by customers.
This method may not be the "bolt on" approach that many are looking for, but if it saves a couple grand in custom shocks, I feel it is worth half a days effort at most.
Our aluminum lower control arms that are in the works will utilize bolt on shock brackets front and rear. We will have the option for extended brackets for our customers that plan on coupling the arms to drop spindles.
Any questions, please feel free to ask.

A mate and I just got our hands on some gen 1 (I assume) units, so keen to check them out and get them on a car.
Thanks for those who poste up some of the traps and issues with them, very handy info to know. We'll likely test fit everything on the bench before fitting them to a car.

Hi guys,
is anyone using the drop spindles on a serious race car (slicks, > 350hp, Aero) and is doing at least sprint format races on tracks like Cota or similar? I am strongly considering to add them to my TimeAttack build, but I have concerns about the reliability of the MR2 hubs. Currently running the miatahubs and pretty happy with them.
Thanks for any insights!

(I suspect that is the set Plohl is referring to in the above post!)

I expect you're the one that emailed us this morning, but figure I'll repost here.
BX1175 hats clear those big hubs no problem Not sure about the rest of the fitment on the spindles, don't see why they wouldn't fit but haven't confirmed it all works with the Keisler spindles.

For everyone else Goodwin told me the 11.75 hats measure 5inch which is 127mm so they told me nope. V8 roadsters on the other hand who makes the hats for goodwin says they "should".
@v8r
Are hats measure 5" at the hub face and then taper out 6". Stoptech hats are about the same. We have some customers using the drop spindles over the years without issue and running our brake kit. This should be the same unless the hub has changed.
