I am thinking about putting front hubs and spindles from a M030 car on my 86. I have a couple of questions about this:

1. Can I use them with my 86 brakes, 86 offset wheels (fuchs and PDs) and other suspension bits?
2. What other parts do I need to replace when installing these?
3. How much does a set usually run?

Thanks

You'll need the spindles, hubs, S4 calipers (or upgrade to Big Reds if you want), rotors and pads. You'll also want to redo your wheel bearings and I would suggest rebuilding the calipers while you are at it. I would also suggest taking a look at your ball joints and tie rod ends, just for good measure. Bonus points for taking care of the control arm bushings and rear caster mount (use the 968 M030 unit, its VERY nice) also.

You will not be able to use your '86 brake calipers and rotors, and you will also have to change to a late offset wheel, so your PD's won't work.

I got a deal on mine when I bought them, and by the time I am done, I will have about $1600 into the conversion. With the wheels that you will need as well, this will be pretty expensive for you. Unless you are serious about tracking your car, its not necessary to do this, in my opinion. The stoock set up works fine.

Cool, thanks for the advice Scott. That is exactly the info I was looking for. My car will primarily see track duty, but I don't know about serious. I am just learning so I will be on street tires for a little while.

When I do get serious I will probably find a 951S with a cage anyway.

If you are just getting started, the best thing you can do is make sure your car is in tip top shape in its STOCK form and learn to drive it. It will go way faster than you can drive it, and modding your car before you learn to drive it will make it a lot harder for you to learn what you really need to know to go fast. I don't know how many times I have seen new guys in massively modded car get smoked by experienced drivers in much "lesser" cars that shouldn't have stood a chance. Its really thr driver, not the car, unless you are going in a straight line, and heck, anyone can do that.

YEA you did.. and so did I!!

The question of whether you need early or late offset wheels is determined by the control arm. If you use the early control arm with a late spindle, you can use early offset wheels, although you'll lose a degree or two of negative camber adjustment. With the late spindles on early control arms, you can still get about 2 or 2 1/2 degrees negative. If you go to camber plates, you can get more. For track use, later hubs and spindles are highly recommeded because they're stronger.

So will the late hubs and spindles directly bolt on to the early arms? I thought I remember reading something about having to machine something for this to work properly? How about the rear, is the same possible?

smokey

The late hubs and spindles are a direct bolt-on to the early arms, since the ball joint pin diameter is the same. You lose some negative camber adjustment because the angle of the early and late spindles is slightly different. If you want to fit S4 brakes on the '86 951 spindles and hubs, I believe there is machine work required due to the difference in the way the disc mounts to the hub, but the '86 spindles are weak for track work. I now have a 1989 Turbo S, so I no longer have to worry about it, but I fitted the late spindles to my late and lamented '86, which was written off at Mosport last fall.

I am looking for m030 front hubs/spindles if anyone has some.

thnx in advance

At the rear, the '87+ axle/CV is stronger, and is a direct bolt-in to an '86 when you buy it as a unit, e.g at Paragon. There's nothing else at the rear that needs upgrading in terms of strength. (In top level racing, the CV's last less than 24 hours; a race team I know had to have special CV's built at mega$ to last the Daytona 24 Hour race .)

smokey

M030 hubs/spindles may be difficult to find and pricey. It would be much easier, and probably cheaper, to buy '87+ hubs/spindles from a dismantler plus an S4 adapter from Kokeln, Racers Edge, etc.

So could I just buy the 87+ hubs/spindles and bolt on my 86 brakes? I am really just looking for something stronger than the 86 hubs/spindles. I had heard the M030 setup is the best, but I don't know that I will need the best for my car given that I am not running much more HP than stock and not race tires yet.

Also, can someone confirm that the 86 control arms + 87 spindles + 87 hubs need late offset wheels?

Thanks all

Max, I will have a set of '87 spindles and hubs available in the next couple of weeks. You will definitely be able to bolt your current brakes up to it.

Thanks Scott. What about my 86 phonies and fuchs?

Smokey actually answered that earlier in this thread. According to him, yes, you can, altho you will lose a bit of camber adjustability, which can be regained with camber plates. I haven't done this particular trick on a 951 so I can't answer this from my own personal experience. I thought that there was a caliper clearance problem when doing this, but like I said, I haven't done it myself. Also, I know that vendors sell differnet rotors for '86 951s as opposed to the '87-88 951's, so I would encourage you to give Paragon a call and ask them about this before proceeding.
