guys im working on putting a set of t2 front hubs, disc & calipers on my rx2...i already have all the required CAD drawings of the caliper bracket and spindle sleeve to mount the t2 hub on the rx2 spindle...now all the hard work is done so all i need is someone to machine out these parts.. these measurements was done by an aussy friend who had produced a few of these kits and they bolted up just fine...
i already converted over the CAD file to Emachine shop format for the caliper bracket... the spindle sleeve had to be re-drawn using emachineshop and it took about 2 days but it came out perfect using all the CAD measurements ....so what do u guys think? do we have any machinist on da house? if we get 10 sets made up it'll cost about $100 a set , maybe less but right now with just mine its about $500... what about REspeed? do u think they can make these kits from the CAD drawings? i was going to place the order with EMS tonight but decided to see if some of u guys might be interested and maybe we can get a better deal..

 

My ears were burning........


We are working on BB kits for the 2,3 and REPU.

We have decided to do hubs rather than use the TII hubs with a spindle spacer. Reason being Hubs can be made with any bolt pattern, including stock. TII hubs require the 5 lug so you are forced you re-drill the rear axles to have the same bolt pattern.

I can usually beat any price on manufactured bits. If you do decide to move forward with the current drawings please give us a chance to quote.

This is all awesome... I'm interested in whatever the final solution is, but I do like the idea of replacing the whole spindle better, since redrilling the rear is somewhat of a pain, especially when you take the rear drums into account.

OTOH, if there was a complete solution for replacing both front and rear hubs & brakes, that would be ideal. I'd love to move away from the 4x110...

 

well u dont need to redrill the drums out back, its been done before using a 4lug 86-87 hub....i think the 5lug rotors is slightly larger than the 4lug ones so u might need to redrill the 5lug to a 4lug pattern....
i think u might be better to use all FC hub,bearings & brakes because of availability in the future....with a custom rx2 hub u'll still need to use factory rx2 brearings and that might be a problem in the near future...old parts are getting harder to find, plus the rx2 bearings might not handle corning load with a larger tire to well...FC stuff is available anywhere, stronger and newer technology than the old rx2 stuff...
for the guys that want 5lug , then bolt in a 1st gen rear diff and buy the respeed 5 lug axles...

Respeed has alot of new things in the works for us old skool guys and im very happy than finally someone is looking out for us.... alot of custom parts that i was developing on my own is now on the minds over that respeed..

I would like to hear what the customers would like to see. Then we will know how to proceed. We can work with either option.

A) FC Hub Option:
Pros
Larger bearings
Production based parts
5 lug

Cons
5 lug
Hubs only available in the used market

B) ReSpeed Hub Option:
Pros
Bolt on solution, no need to track down FC hubs
Any bolt pattern

Cons
Slightly more costly for the kit. (May be offset by not needing to purchase used FC hubs)
Smaller stock bearings

From my perspective, I'm looking for serviceability as much as better braking (maybe more). I'm in the middle of a '73 RX2 restore (going oh so slowly) and one of the ongoing roadblocks is that much of the braking system isn't available anymore, much less wheel bearings and other necessities.

I'd really like an "all in one" solution that addresses the wheel bearings, hubs, bolt pattern, and brakes.... And one that uses recent enough bits that getting parts for a while won't be a problem.

What about using brake components from another car entirely? I know its somewhat blasphemous, but the Ford Mustang PBR-made brakes on my XR4Ti are fantastic - two piston, very light, and dirt cheap ($40 at Autozone...). Just a random thought...

 

Billy, any ETA when those REPU big brakes are coming out? No rush but I'm almost certain I'd go with what you are offering vs. having to do a one-off setup.

As for the RX-2 brakes: I agree with Thesameguy that future service is a concern. Plus I'd rather have larger bearings that could handle more stress.

Ever consider a kit that allows the old school cars to run SA22 or FB spindles? That way we can just buy your FC caliper bracket and sleeve while using the larger diameter 84-85 RX7 front spindle. That is my plan for my RX2 but the problem is the steering knuckles.

Billy, the easiest thing would be to make a roll center block that goes from the RX-2 (R-100 is supposedly the same) steering knuckle, then is slightly offset, and bolts to the 1st gen RX7 spindle.

 

this could be done but it wont be cheap...
parts list to mount 1st gen spindle/strut on the rx2 would be custom cuz of the major camber problem u'll face by using this rx7 spindle...i've looked into all this already and the most cost effective and easiest way was to use the rx2 spindle and just adapt stuff onto it...
for starters u'll need a new custom adjustable lower control arm and rx3 steering arm to make it work 100%... lower control arm will help u get the camber back to stock..the rx3 steering arm will help u to mount the lower joint to the spindle because the rx7 ball joint has a larger taper than the rx2 steering..rx2 streering arm still wont work if u open up the ball joint hole, because the 2 outter holes that bolts to the spindle wont line up....

heres something that might work and might be less hassle in the long run but will cost more money

new custom lower control arm with rx7 (86-95) or miata lower ball joint
new custom steering arm that will allow the newer style ball joint to connect to the 1st gen spindle...
also, that custom steering arm should be made to work with the 1st gen rx2 tie rod...
the only custom peices are the control & steering arms...
what do u guys think?

 

I actually have a RX2 spindle torn down right now as well as a 1st gen RX7 spindle so I want to adress this whole camber issue once and for all. I think this issue is over exagerated but I'm willing to take another look and take some measurements.

If the camber was that different it can just be adjusted for in the RX2 to RX7 roll center blocks. This (negative or positive, not sure) RCA plus the rx7 spindle would be the only parts needed. You are still using a RX2 lower control arm and steering arm (knuckle) that bolts to the RCA, which then attaches to the RX7 spindle... that's it.

I'm not at all in favor of using the RX2 spindle if possible because of the lack of parts support and it's dainty size.

Could always use a Toyota spindle too. They have a big selection of strut inserts plus 4x114.5 bolt pattern! Oh the choices...

 

I'm certainly not qualified to comment on any of the engineering or compatibility here, but I'm 100% behind getting away from the NLA RX2 parts as much as possible. Given the standard McPherson strut + LCA layout, there must be dozens of cars to scavenge parts from...?

 

The NLA problem for RX2 parts is being addressed. Patience grasshoppers............

 

I think we have a good plan to move forward. It actually involves both ideas for the brake kits. We will start moving forward.

It doesn't take that much of a camber difference to worsen an already bad problem. Having positive camber on an RX2 that already can't track straight is asking for problems.

On another note, not to **** on REspeed's efforts, because we need it, but there are options out there. I went with The Racing Store's custom brake package. They sell a very nice kit for a reasonable price.

 

Hmm.. Is it an upgrade kit or just stock replacement..

I'm getting a 12a put in within next month or so. I would love to get my duece running and start restoring it.

 

I have been getting a bunch of questions on the build that I am currently working on. I will put up the pics I have tonight when I get home.

 

Any word on this?

 

well all my drawings was handed over to ReSpeed and i think they were going to put the kit into production...i've moved on from this brake kit because there's some limiting factors for my project by using the rx2 spindles...i've now opted to put a full t2 front suspension in my car that will handle what ever i have to throw at it...its been done before & i've seen it in action a few weeks ago while i was on vacation...Billy you could still hook a brother up on a free kit for future projects, hehe ;-D

 

sound pretty good im down for what ever comes out first

 

Does anyone know what came of this???

 

I'd like to know too!!

 

Don't know if this was an old thread. But anywho, I vote for a Hub vice a spacer because it provides better options in lug patterns and offset. I'd be interested in two sets for RX3 if you guys ever get around to make them. One set 4x114mm (86-87 2nd gen) offset, and one 5x114mm tii offset.
