I'm putting together a package for an S60 for my 02 Z28, and I'm currently looking at a stock width S60, 4.10 gears, s-trac, a BMR T/A and crossmember, new driveshaft with forged yokes(not sure which one yet), arp wheel studs (not sure what size, should I got 1/2"?), if there anything else I should get while I'm doing this?

Car is for the street and strip, and currently has MWC LCA's, a MWC PHB, strano swaybars, strano springs, Koni SA shocks, and LCA brackets.

I'm running a 315 toyo DR for the street, and planning on getting some 15's and a slick for the track. Anything I might wanna look at swapping out while I'm putting that beast of a rear in there?

Did a search and there a few folks getting wheel hop issues, is that a common thing? other than that and the weak stock wheel studs there doesn't seem to be much else that could be an issue.

Thanks for the help as always

I would step up to the 1/2" studs.

Why not go with MWC's Fabbed 9"??


those S60's are HEAVY. I sold mine for the fabbed 9"


It comes with a torque arm and is a **** load lighter...

There are guys knocking on the 6's with his setup. So I hope your reason isn't it has a bigger ring gear is stronger....


1/2" studs are a good ideal.

Pretty much cost. To get a fab9 the way I would want it built although it would be better is more than I need to spend. Im not racing competitively, and Im not terribly concerned about how it handles due to the weight increase. I just want to be able to put some sticky tires on at the track sometimes and not worry about breaking ****, and the s60 does that cheaper.

MWC Fab9 here. I almost bought a S60 because of the price and I am so glad I spent the money for the MWC rear.

Heres another question, for a street car would I regret losing ABS? Its $150 more to keep it?

Myself, I would not worry about losing the ABS. I can't even remember the last time my ABS kicked on even during hard braking. Of course I don't drive my car in rain or snow either.

just some facts I found myself. looking at both rearends.
S60 is about 50pounds heavier non spool, then a 10bolt (200-150)
Spool is 25-30pounds lighter on them (9.75 ring gear is big, s60 spools are 14ounds) so a truetrac style s60 is gona be alot heavier then a spool one. My spool s60 with BMR LCA brackets, transverse shock mounts, stock width is about 165-170 pounds, but I trimmed up some extra metal on it.
Max light weight you can get a 9inch lighter then a 10 bolt it it cost some money. gun drilled, narrowd, light everything. I price up a MWC setup to be lighter then 150pounds and it was about 4K with the TA. I could only sell my old TA for a few hundred. So to go it a MWC 9 over my s60 was about 1K to save 35-40 pounds. But it you dont have any rearend or TA going the MWC is better at that point, Most people already have a TA and Xmember at that point.
You can get a spooled s60 for about 2,150 shipped to you, thats ready to bolt in, and you get it in about 10days maybe 2 weeks. Not gona get a fab9 that close more like 4-6months, But for a race car, it has more things your like.


If you get any rearend. I would get the axles drilled for 12mm studs, 1/2 and 5/8th. Down the road you'll be happy, it cheaper to get it down when it getting all built new, then doing it later, with shipping, getting new seals,bearing, using a press ect. And the re-sale alot better on the rearend if it will work for more people.

If you use stock brakes for now, slot your backing plates so you can get them on,off the axles around the bearings. Do that now, every time you want to get them off your gona have to damage the seals, and bearings pulling them off, or cutting them off to get the backing plates off. I forgot, I think its 50-60$ per side for bearing and the seal on a s60. And it adds a extra 1-3 days in getting the car back together when you have to do that. Look at how the strange some some aftermarket backing plates are, and slot them like that now.

Just remember that MWC has an expedite option for the guys that do not want to wait that long. I had mine in 4 weeks, but I had to pay a little extra but it was worth it IMHO.

I think Eric said that my Fab9 weighed in at 186 dry with 4.30s, 35 spline axles, s-trac diff, and iron center, don't quote me on that it's been 6 months since I picked it up. The MWC full length chromoly TA is LIGHT, I didn't weigh it, but my UMI full length arm felt 2x heavier. Also have chromoly LCAs and their chromoly watts link. Those parts are also very light.

I could cut a few pounds by getting an aluminum center, gun drilled axles, and adding some lightening holes to the LCA mounts and trimming off the PHB mount.

I'm 100% happy with the MWC axle. I did the suggested break in period and changed the fluid at 500 miles. I have heim joints through out the rear suspension and ZERO gear whine. I also have removed the back seat and you still can't hear any whine My 10 bolt sounded so angry lol its nice to not have to listen to any gear noise.

im hoping to kill my 10 bolt in the spring so i can stop procrastinating.

also i was told not to get drilled axles because theyre bad for the street.. cant remember the resoning off the top of my head.

So you can order an s 60 without backing plates and add slotted backing plates later without taking apart the rear?I want to order a new rear but I am not ready to take my 10 bolt apart yet.Does anyone have a picture of the slotted backing plates?

S60 is a great rearend, but it is quite heavy and there are limited choices for gear ratios. It will come with 35 spline axles and diff unit as standard features. The S60 will be about 2700.00 with the 3ch abs, LCA relocation brackets and no torque arm. A good torque arm thats even close to comparable to the MWC unit will run 500.00-700.00.

The MWC 9 even with the iron center will be only a few pounds more than the 10 bolt. Comes with it's own exclusive chromoly adjustable torque arm and crossmember for your application. Includes all necessary little things like brake line clips, brake hose mounts, e-brake cable brackets, sway bar mounts, drain plug, chassis brake hose adapter, and the LCA brackets are 4 hole adjustable as standard features... not an ad-on. The MWC 9 with 3ch abs and posi diff unit will be about 3185.00 shipped.

SO... to put apples to apples by the time you add it all up the MWC 9 is just as good of a value.

Right now the 9" rearends are only a couple weeks to get built as we are pretty well caught up from the in-season deluge of orders.

Yes... the S60 can be had with or without backing plates. The mod talked about earlier requires saw cutting of your oem caliper mounts and will most likely render your e-brake useless on 98-02 models. New aluminum backing plates are included from Strange on 93-97 models.

hmm. well this swayed my decisions

Well I decided to go all out and ordered a MWC 9". When you get down to it, an S60 with a driveshaft and torque arm is nearly $4k. The 9" is closer to 5, but has MUCH more potential for the future. When you also factor in its all fabricated (and very well supported) by a small shop, IMO its the better value.
