COMPLETE "BOLT-ON" 5-LUG CONVERSION SYSTEM

I've put together a system based upon solving the problems most people would have with converting the rear of a 914 to the Porsche 130mm 5-lug spacing.

Most people don't have access to a press or the tools needed to get bushings and bearings in and out. This makes the current 5-lug kits that are on the market rather difficult for the average home mechanic to install. The front conversion can be as simple as bolting on a 911 suspension, literally, a bolt on application. Why not the rears?

This is where the "Rear 5-lug System" comes into play. The process:

1. A clean and straight set of core control arms is stripped and bead blasted to bare metal. Bushings and bearings are pressed out.

2. The bare control arms get coated with 2 coats of "Zero-Rust" protective paint.

3. New bushings and bearings get installed.

4. A set of core hubs gets drilled to 130mm 5-lug spacing. A set of custom ring bosses are machined to go under the additional 4 studs to strengthen the mounting surface and bring them up to the factory 11mm boss height. New studs are pressed in and each ring boss gets tacked (MIG welded) on to the hub. Then they're coated with 4 coats of enamel.

5. The 5-lug hubs get pulled into the new control arm bearings and they're ready to ship to you.

6. You simply bolt on the new 5-lug control arms and put your cores in the box and ship them back.

Cost is $395.00 plus cores and shipping to and from 84092. Shipping weight is 50lbs and can be figured by using this site: USPS Shipping Calculator

5-LUG BOSSED HUBS

I also have the 5-lug bossed hubs for sale separate for those adventurous mechanical types that want to install their own bearings and pull in the hubs. These hubs have custom ring bosses installed under the additional 4 studs to strengthen the mounting area and bring them back up to the factory 11mm boss height

These are 914 hubs designed to work with 914 stub axles. If you have purchased 914-6 stub axles, you'll need to purchase an early 911 rear hub.

Cost is $145.00 plus cores and shipping from 84092. **UPDATE** Shipping is now a flat $8.10 for Priority Mail to anywhere in the continential United States. For international orders you can still use the USPS link. Shipping weight is 11lbs. and can be figured by using this site: USPS Shipping Calculator

AN EDUCATED CONSUMER IS MY BEST CUSTOMER

Hey Kevin,

No, I charge "Actual Shipping Charges". I've found the complete trailing arm systems range from 48 to 50lbs. boxed so you can use those USPS Shipping Calculator links to add your zip and get the "Actual Shipping Price".

I'm not in the shipping business, or shall I say the business of making money off shipping. I make a small amount of money from the labor involved in:

*Pressing out bushings
*Removing Hubs
*Removing Bearings
*Bead Blasting Arms
*Painting Arms with "Zero-Rust"
*Installing Bushings
*Installing Bearings
*Machining hubs with ring bosses and
*Installing hubs

When you add up all the time involved in those processes you'll see what a bargin these systems are. All so that I can offer a bolt on solution for those who don't have the special tools or the mechanical inclination that other kits may require.

I've found that you can easily find 69-73 911 front suspensions that will "Bolt-On" to your teener, giving you a slightly larger torsion bar "and" vented 911 rotors that you won't have to re-machine every time you want to change rotors. These systems can be found for roughly $250.00 (max.) I've found my last two front (911T) systems complete with M-Calipers, a-arms, struts, hubs and crossbar for $150.00

So... when you cost out my 5-lug "Bolt On" system (others require you do all the work listed above), again, you can easily see that this is the most cost effective solution on the market:

My Rear "Bolt-on" System = $395.00 ($349.00 with reusable factory bushings)
You'll need 914-6 Rotors = $110.00
Front 911 "Bolt-On" System = $150.00 - 250.00 (or less... shop around)
Total System = $655.00 - 755.00 ($609.00 - 709.00 with reusable factory bushings)

-or-

"Roughly" the same price (or much less) as "other" kits on the market that make you do all the work (pressing out bushings, removing hubs, removing bearings, installing bearings, hubs and new bushings). (IMG:http://www.914club.com/bbs2/style_emoticons/default/smash.gif) Other kits use your stock 914 front brakes, solid 914 rotors and 17mm torsion bars. Rotors that you'll have to have re-drilled at a machine shop every time you need to change them (ever had a warped rotor?). And no new bushings... (IMG:http://www.914club.com/bbs2/style_emoticons/default/sad.gif) If you do your homework and are a frugal buyer, you can save yourself some serious money and have a much better system. (virtually identical to what the factory put on the 914-6)

Thanks for asking Kevin!

I wish you'd offered these before I bought those calipers from ya. Some great information there. I wish I'd known all this before I started tearing things down. I'm wondering if it's not too late. Do the 914/6 rotors work with the 914/4 calipers? or is it an altogether different "animal"?

Hey Carlos,

914-6 rotors will work with 914-4 calipers. There have been a handful if instances where the 914-6 rotors were 1-2mm too large in diameter. From what I've gathered 98% of them will simply bolt up.

For the remaining 2% I would recommend grinding the inside of the caliper so it will fit with the 914-6 rotor. Others turn down the rotors but, you'll have to do this every time you get new rotors.

I am interested in a pair of hubs.

Can the cores be any 4-lug? (Is that what the afore mentioned "ring bosses" are for?)

Are the studs included? If so, what length, and can they be changed out for longer studs?

Hey John,

You're correct. Any 4-lug hub will do. That is what those ring bosses are for. Other hubs on the market are spotfaced to 3mm and studded. Not much for your studs to grab on to. These "ring bosses" bring the stud boss back up to a factory 11mm spec that matches the original.

Studs are included. Special length studs are extra depending. Any stud or length of stud can be used. It takes a bit longer than standard "off the shelf" hubs because I like to take a sample stud to the machine shop to get a perfect fit. All studs are not created equal. If you want to get the studs and send them with the hubs you can deduct $20.00 from the price.

If you're doing PCA with stock Fuchs wheels, 72mm with an open nut is the minimum. If you're using spacers, add the width to that measurement. 72mm gives you the 14mm beyond the end of the nut required. For racing I recommend Verbus because they have full engagement.

Hope that helps,

Eric

Eric,

The refinished arms and hubs look great. (IMG:http://www.914club.com/bbs2/style_emoticons/default/smilie_pokal.gif)

Can you describe what type bushings are used? Are these subject to the typical creaking and binding of delrin and other plastic bushings?

Thanks.

Hi Mike,

I use the standard Weltmeisters for most rebuilds. I can use whatever the customer wants however. We now stock Elephant Racing PolyBronze bushings and sell the as a system (see ProArms toward the end of this thread).

Yes, they are subject to creaking and squeaking which is why I dremel 4 grease grooves on the inside of the bushing and load them up with Mobil 1 before I send them out.

I like to keep the original bushings if they look good but now-a-days most aren't looking so good. When I get a set they go for $349.00

Hope that helps...

E.

Hey Chris,

The USPS Site says...

Priority Mail 2 Day(s) $42.15
Parcel Post 4 Day(s) $19.17

I find they usually cost around $19-20 to ship a standard set. I just did a macho 911 e-brake, set with stiffeners for Greg DeBord that was 60lbs and ran around $33.00.

If you're talking just hubs I have good news: The hubs will now fit in the new "Flat Rate" box. The new box is 11x9x6 and is only $8.10 and ships Priority in two days.

Eric,
Do you do these with the 911 ebrake set up? I have 911 hubs and CV's that I would want to use due to me going V8...
PM me with an idea on costs, if you will do this sort of thing-
Thanks

Hey Thom,

I do offer the 911 e-brake conversion. You supply the e-brake assemblies and add an additional $150.00 for the welding and grinding needed.

I just finished a set with stiffeners and 911 e-brakes.

I highly recommend Eric's 5 lug hubs. He does excellent work! If I had more money I would of defanitaly gone with his complete trailing arm set up.

Thanks Again,
Josh

If I bought some new front rotors and your rear arms/5lug conversion to go with my rear calipers I just paid for, could you drill the front rotors to accept 5 lug so I don't have to go to the 911 suspension yet?

Bob,

Sorry I missed this post. I'm currently "Browser Challenged" .

Yes, we could drill your front rotors while you search for a 911 front suspension.

Let me know if you want just hubs or the complete bolt on kit.

Eric

P.S. Your calipers should get there today.

Eric what about studding a set of 4-lug'ers?
Any value in you "ring boss" treatment?
