Just that.

Are 90' S2 spindles, hubs, and calipers the same as late non-M030 951 stuff?

I'm trying to find a set of good late 951 hubs and spindles for my early NA to convert to turbo brakes. If the S2 stuff is the same, I might be in business.

Then I'll just need some rotors and calipers.

I think the S2 is late model 951 equivalent both with and without M030 option respectively. In other words both cars could be had with and without the M030 option.

But I'm not 100% on that.

Not the same since 89-91 Turbo's have the larger brakes. A carry over from the 88 Turbo S with the M030 package as standard.

They are not M030 spindles (meaning turbo S).... those are easy to tell. ^

All I want to know is if they are equivalent to standard 87-88 951 spindles.

I think (hope) Tony is right... but since he isn't sure, I'll take a few more answers.

The only thing that may be different is the hub diameter. They changed it at some point, as 91's do not require spacers with later wheels like all of the others.

Otherwise, they are the same.

I am going to eventually have a spare set of calipers and rotors, as I've bought Turbo S brakes for the track car. I wasn't planning on changing them until I needed new pads or rotors, but I might be willing to go ahead and make a change.

I have read that the struts are different, and that the spindles can't be changed without a strut change. Have you looked into that?

87-88 951 is not "late" 951 by any standards.. Late 951 is turbo s -88 and 89-91.

Yes all late offset regular Turbo,S2, 968 spindles are the same(excluding TurboS, 86, 89,MO30). There are some minor variations in calipers but they all interchange and work. I have rotors and calipers if you need any. I even have a set of 968 spindles, but they are my spares and not for sale.

Some of the 87/88 spindles were not machined for the ABS sensor as ABS was an option in those years. Even these can be drilled for ABS. If your looking at 90 S2, it should have the ABS sensors not that you need them. Late offset, non ABS spindles are generally cheaper as there is little demand for them.

S2 = 87 & 88. 'Same'

Duke - over here we usually refer to the 86 as early and the 87 and later as late... the 88S and 89 are just called Turbo S parts.

I have a set of '87 951 spindles for sale, if that's what you need.
I also have '90 S2 spindles, but they have the provision for ABS so i was planning on keeping them.

Duke

You guys need to correct your definitions considering the 951 was manufactured until 1991

When it comes to the larger brakes however, the M030 is useless as a definition as the larger brakes were standard on the 90-91 models even though they did not have M030 from the factory. To avoid any confusing it's best to refer to the different 951 brakes as 220 hp model or 250 hp model

Regardless, the "early" and "late" differences are most frequently used to describe the offset. The 89+ parts are usually referred to as Turbo S (though it lost that designation). Did the S2 with the M030 option not have the bigger brakes (whatever you want to call them)?

How much do you want for your spindles? Do they also include hubs?

The S2 spindles I have my eye on Do have the ABS holes...which I will plug. I would be willing to trade anyone for some non-abs 87 spindles if someone wants them.

I know the struts are different...but its an easy fix.

OH, and thank you everyone for you help.

I have hubs to match the spindles. They have brand new Timken (made in US) bearings/races with under 1,000 miles on them + new grease seals (have the receipts). Packed with a real bearing packer and good grease, and done right. They're ready to go!

Price? I don't know what they go for, honestly! Make me a fair offer (fair to both of us) and they're yours!

Anyways, i'll PM you about it.

The M030 option on the S2 and 968 is the same front suspension as the Turbo S (except the sway bar on the 968 M030 was larger)

Most 87 and later spindles have the ABS mounting provisions – even if the car did not get the ABS option.

Oh yeah? Well then you need to make sure you identify the US models by their correct specs – ours were only rated at 217hp and the ‘Turbo S’ and 89 turbo were only 247hp….
