I have an opportunity to purchase a set of the 4 to five lug adapters. They are quite a bit less expensive than swapping out the original hubs with those of a 911 and then having to deal with rotor brake issues. Is this a alternative that will work? Does anyone
Have any experience with these adapters?
Thanks in advance

Generally bad. Often made of weak cast aluminum. Some are made of billet aluminum. They also offset the wheels outward. I have a set I will not sell and will probably scrap for safety reasons. Eric has a great write up on options of five lug conversions.
My preference is 911 front suspension and redrilled rear hubs.
What is the plan for the car overall and what kind of HP will it have ?

74 with a 1.8 liter running the stock EFI and Dansk exhaust system. Nothing to much over what the original build was. Just looking for a well mannered fun car to drive. But really like the ability to have a five lug set up.

Thank you for the link, just got finished reading it. Excellent tech info especially liked the way Eric took the time to go through the pro and con, using costs, what the cars uses would be and so on. Definitely saved as a favorite.

Bruce, wouldn't re drilling the rear hubs make them weak? reason I say that is because only one stud will be entirely in its own boss, compared to the others either half way or not at all?

You will be limited to high offset wheels. Boxster fronts, maybe modern 911 fronts if narrow enough, and I think some of the phone dials.

The redrilled hubs from PMB would be the much better way to go if the 911 parts are out of budget.

Rear hubs have been redrilled for 30+ years, I've never seen a failure, some people (like PBM) add a spacer for a little more surface area.

sort of brightened everyone's day for a minute anyway.

Yep sorry for the mis cue. The photos were just meant to show a representation of the physical part. They do come in various bolt circles. I appreciate the attention to detail though.

On a side note, I see the adapter come from "Raceland".
There is no racing organization that will allow you to use adapters while racing.
Consider that if you ever want to autocross or DE or..... Drifters might let you. (IMG:style_emoticons/default/laugh.gif)

Actually on further consideration it looks as though the rules have changed?
It looks as thought SCCA may allow them?

As this post goes and the more I read up on adapters they appear more likely to fail and a way to "get by" on the cheap. While I do not see me racing the car I want the car to be done correctly. Scratch the adapters.

Eric has a comparable setup and you would be dealing with a reputable vendor not like George.
Another reason to not use adapters is they add one more component to allow for the wheels to be more off center. It can already be a problem on the rears that are not hub centric.

I am not a fan of the front redrilled rotors for the following reasons:

1. The studs go in a thin area of the rotor and can strip out. Eric's setup uses red loctite to install the studs but with use of an impact in the nuts you can have problems.

2. If they do strip out, or the rotors need to be replaced, you cannot easily get an off the shelf rotor to replace it.
