That will work too.  My adapter plate bolts to the oem fiero spindle.  My problem is that the oem caliper mounts to the inside of the mounting arms and the Corvette adapter plate bolts on the outside surface.  I'm going to have to remove my spindles and mill the arms flat and on a 90 degree to the spindle.  As it is now, the caliper is cocked.

It's your call.  Either cut the rotors down another .050" or get out the dremel.  I wouldn't mess with the mounting holes.

thanks 01

Took off .030 which reduced the diameter by 1/16.  Taking another .050 would reduce the diameter by another ..... well that amount is too much.

I have another set of brackets to play with :LL:  dropped them off at a "real machine shop"  :o owned by my friend.  Either adjust the caliper holes or make a new bracket that works.

Richard at Arraut Motorsports is a nice guy but the product is sloppy. As my machine shop friend says... "what kinda crap are you bringing me now?"   :LL:  told him I still have the rear brackets to go..... ::toothy  888o  .

Back at it after the holiday of eating/drinking to much, and tolerating certain family members  ;)

The drivers Arruat bracket and rotor came back and was machined the same as the now working passenger side.

Well The drivers is more out of wack than the passenger side.

The upper area has clearance the lower is still off and rubbing.  After screwing around with it for a couple of hours, I've come to the conclusion that the  caliper holes in the bracket,  will have to be redone about a 1/32 to 1/16 of an inch.  :o :P 888o ::)  ::scratch


If any body has seen this before and has a solution ......

The calipers on the rear of the fiero sit opposite to the Murcielago placement.  the standard Arruat rear brackets follow the fiero location.

New V2 bracket put the caliper more inline with the Murcielago..... although the 4 piston caliper is small.

The rear bracket has to be machined a bit more to correct the rubbing issue.

Sweet!! just in time for the weekend my extended heat treated chromoly 300 axles arrived today!!

Initial quickie measurement on the right axle would make one believe it was done correctly ::toothy ..... but the proof is in the pudding!!

After a couple of trips to the machinist to correct the Arraut Motorsport wonderful product  ::scratch   The front wheel can actually turn now with the tire mounted!!!

The drivers side is next and that will be back tomorrow, since it is known what has to be done to the system for it to actually work!

The example picture I was looking for that I knew I had  , but couldn't find. Makes these suggestions have a bit more clarity.

Thanks For the picture it is worth a thousand words !!

To get more room by the side of your handbrake lever , you may want to consider mounting the seats in the OE orientation which is inwards at the front and not parallel to each other.
There is also an angle to the steering column , but that may be a step too far...

Thanks String! that is a great idea, wouldn't have to be that much and not really noticeable.   A simple solution for a Simple REDO ::toothy

Got the switches for the REDO on the steering column.  Besides having drops of resin and paint over spray, the car must have been in the sun/weather as they were really rough and beat to hell.  ::)

The pictures dont really show how bad they are!

Probably wise to use the old ones until this build closer to being competed  :LL:
