Questions arising during brake caliper refresh
 

Hello all, first post here.
I have an '84 Targa with a gorgeous whale tail that I bought back in January. I am in the process of rebuilding the calipers and I ran into some issues that searching the forums did not quickly solve:

1. Where does the lug wrench normally live inside the car? I have a jack mounted in the frunk, but I was not able to find a lug wrench up there.

2. Does anybody recognize these wheels?

I am replacing them with either original Fuchs or Group4 Campagnolo reproductions, but I was wondering if there was any value for these aside from scrap.

3. My lug nuts were 20mm, but I thought this cars would take 19mm nuts. Is that correct?

4. Any recommendations on removing the spring clips from the brake line tabs on the car? I have not been able to get mine loose.

5. There are still no hard recommendations on jack points for the quick jacks, correct? I got mine up by putting the blocks close to where my local porsche shop lifted the car before, but it was nerve-wracking. Once the car was up, it did feel pretty sturdy.

6. Back on wheels, on this guide Wayne implies that the widest wheel that a 911G will take is 7in without flaring the rear wheels. I thought that 8s were commonly run on that generation. Is the discrepancy just down to tire selection or am I screwing myself if I source some 8in thick wheels?

Welcome! Nice looking car.
1) The wrench should be in a tool bag with several other tools. These sometimes are missing. 2) I don't recognize the wheels. Looks like they are off a Boxster or 996 but I am totally guessing. 3) The stock lug nuts are indeed. 19 mm. 4) I have had luck pulling straight up with some pliers. If they are hard to budge, see if you can wedge a screw driver at the bottom of the clip to pry them up carefully.
Not sure about 5 and 6. Good luck!

Thanks for taking the time to reply. Either I just don't have a toolkit, or I am an idiot when I poked around for one. Probably a bit of both! I'll have to build up my own, with a 20mm wrench for now.

1. Lug wrench is in the toolkit. It's not what I would reach for when working on the car in the garage. Get a breaker bar or impact wrench if you want to spend money.

2. Those wheels look like the turbo look wheels from the 986 Boxster.

3. 19mm are the OEM size that came with Fuch wheels.

4. Squirt them with your fav penetrating oil, grab the angled edge with pliers or vice grips, then whack the plier/vice grip with a hammer to "tap" them off.

5. I don't use a quickjack, but the corners of the tub is good in general.

6. Lots of people run 8" width, even 9" out back. Depending on tire, you may end up rolling the lip of the fender for more clearance.

Welcome to our BBS. Lots of good information here. The search function is your friend.

Looks like most of your questions have been answered.

This thread shows what your factory toolkit should look like, yours would be similar. If you have the owners manual for your car, a picture is in there. http://forums.pelicanparts.com/porsche-911-used-parts-sale-wanted/839400-fs-nos-1974-89-911-tool-kit.html

Bill Verburgs diagram shows jacking and support points.

This drawing by Icemaster updates Bill drawing above to show locations for supports (the O's) but you will be hard pressed to put a jack on these points.

One reason the QJ may be making you uncomfortable is that you have it backwards for a 911. The pump should be at the front, with the hydraulic cylinders pointed at the heavy (rear) end of the car. Here is a good thread with QJ tips: http://forums.pelicanparts.com/porsche-911-technical-forum/962917-looking-feedback-quickjack-users.html

For lift points you want to use the X on either end of the "D" dimension, then for the front you use the roughly 90-degree pinch welds between the "C" and "B" dimensions. The QJ frames will be on the inside of your wheels.

For a tool kit, that linked thread gives you a rough idea, but there are numerous differences in the tools from 1974-1989. This site looks pretty good, seems to cover the subtle differences: https://www.originalporschetools.com/

And I've been trying to consolidate some of the better references here: http://forums.pelicanparts.com/porsche-911-technical-forum/1065098-85-toolkit.html

Thanks for the reply! I have been successfully using the search function for the past few months, but I unfortunately did not know enough to find those posts that you mentioned. Looking for 'quickjacks' didn't have any solid answers, and "lug wrench location" similarly didn't yield much aside from some discussions about whether there were tie-downs for the tool case included on the car somewhere. It's hard to find something if you don't quite know what to call it! I definitely can find that wheel depth information, now that I think of it, but I slipped it in there while asking my other questions because I got excited.

Thanks for those photos. Luckily I am jacking up on some of those points. A previous owner put some dents in the floor with bad jacking, so I definitely know where the wrong spots are!

One more question - what does "BBS" stand for? I only know that as a wheel brand.

Thanks for the reply! I do have a breaker bar, I was just assuming for no good reason that the lug wrench would be packaged with the jack, as was the case with a lot of my previous cars. The lug nuts on my car were way over-torqued; I destroyed 2 3/8" socket extensions trying to get them off before soaking them in penetrant and moving to the 1/2" breaker bar, which may now live with the car:

So much for craftsman quality!

And thanks for the advice on the clips! Just went downstairs and hit them with penetrant a second time. Hopefully I can finally get them off tomorrow!

8” wide Fuchs
 

If you are going with 8” wide Fuchs wheels, be sure to get ones with 10.6 mm offset.

Yikes, those must have been tight.

I bought a Milwaukee impact wrench years ago and it is such a time saver. I only use it to remove lug nuts on the 911, I haven't needed to break it out for anything else on the car.

But other cars, daily drivers, trucks...indispensable.

Ouch! Lucky your socket did not break.

Going forward, always use impact sockets and extensions for this service. They are designed for the high torque generated by an Impact Gun or a giant breaker bar.

Funny enough, that is how I started, but my Makita Impact driver could not get these lug nuts un-stuck! I felt like I was losing my hearing from running it so long. They were WAY over-torqued. My "calibrated arm" would place the torque at somewhere between 100-120 ft-lbs once I finally got them off with the 2-foot breaker bar, and that was after they sat in PB Blaster overnight. The things that some people do to their cars!
