BoostedBalls Posted June 16, 2005 Share Posted June 16, 2005 I'm sure someone here has done this, I just can't seem to find any info on it. I have the 4x140mm hubs and I'm wondering if anyone has redrilled them for a more common 4 bolt pattern. I'm not sure if the hubs have meat in the right places to make this possible. I may even consider welding my holes shut and starting fresh. This would be plan 'B' as the heat temper of the hub will be changed with the welding. I don't want to go with a 5 lug setup. Thanks guys! -Chuck- Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted June 16, 2005 Share Posted June 16, 2005 well there have been one or two people who have redrilled their hubs to a 4x100mm pattern but I know one guy is located in Aussy. Why not go the 5-lug route? If you do, then the options for brake upgrades and custom suspension comes into play, making the RX handle like its on rails. In the front of my RX, I currently have '95 Impreza struts (soon to change when I get some extra cash), Impreza hubs, Impreza rotors and calipers, Impreza axles, XT6 control arms, XT6 tie rod ends and XT6 swaybar. In the rear, I have XT6 hubs with rotors, XT6 swaybar and XT6 calipers. I also have a set of coilovers for the front and rear as well but I haven't installed them yet. Compared to redrilling the hubs, this was a walk in the park. Now all I have to do is bleed my brakes and get an alignment. There are so many options once you convert to 5-lug compared to the 4-lug... Quote Link to comment Share on other sites More sharing options...
Numbchux Posted June 16, 2005 Share Posted June 16, 2005 it's probably possible, but the advantage to redrilling to 6 lug, is you can use 2 of the lugs to make sure it's centered. to pull them all out and start over would make it very hard to center the wheels on the hubs. Also, you'd have to make sure to get a wheel with enough room in the middle for the axle nut. it's worth a try, but be very careful, and measure it out a ton. Good luck!

TurboSPFI Posted June 17, 2005 Share Posted June 17, 2005 or get very lucky like i did.. the two holes that line up do a VERY good job of keeping things centered Quote Link to comment Share on other sites More sharing options...
BoostedBalls Posted June 17, 2005 Author Share Posted June 17, 2005 Well, I said I didn't want to do a 5 lug swap but maybe it's the way to go. I need to do some more research. This is a race only car and I would like to make about 300HP and be able not only stick it to the ground but stop the car just as fast as it takes off. The Impreza suspension is different than the Legacy? Can I use my RX axles? Can I keep my LSD diff? What brakes do I want? Provisions for parking brake? Hmm, what else? -Chuck- (diving deeper into my project than originally forecasted...) Quote Link to comment Share on other sites More sharing options...
bratsrus1 Posted June 17, 2005 Share Posted June 17, 2005 Hi This is Jerry, yes i have done this on my hatch. The bolt pattern i have is 4 on 4 1/2 and that is mustang 2 or toyota. I will have my car at the show so everybody can see it. I am also drilling another set of hubs to 4 on 4/3 to fit a set of stotted mags that i have. Thanks Jerry Quote Link to comment Share on other sites More sharing options...

TurboSPFI Posted June 18, 2005 Share Posted June 18, 2005 why? i just bolted the hub up and used the other 2 holes (the ones with the studs knocked out) as a drill guide.. i have no balancing issues and my car goes down the road smoothly.. thats why i said, or get very lucky like i did..

PoorManzImpreza Posted June 19, 2005 Share Posted June 19, 2005 not hijacking but wagon rear calipers have bigger pistons than xt6 calipers FYI... there is an ea82 wagon in aussieland that has subaru 4 pot calipers and discs on the front and 2 pot calipers and discs on the back.. sourced from a JDM wrx..these are the black calipers with subaru written in white as stock..the guy had painted em red like evo brembos once u go 5 bolt this becomes possible..2 run 2pot in the rear u gotta adapt the leading and trailing e-brake shoes and backing plate from the same parts car u sourced the brakes from to the stock ea82 hub. With some drilling and spacers it will bolt 2 the same 3 holes the stock ea82 caliper mount/backing plate mount 2..then u gotta figure out how 2 route cables to the ebrake levers..the front is bolt on if your using 'GC8' sourced 5 bolt stuff which will bolt onto xt6 lower control arms which if 4wd will bolt to any ea82 front suspension mounts..u gotta use the ea82 top hat on the impreza strut.. oh and these brakes require 17" wheels or special 16s 2 run.. the rear xt6 5 bolt hub bolts to the ea82 spindle..if u keep stock brakes u need the xt6 backing plate/caliper mount as the xt6 rotors are bigger in diameter thus the caliper mount is further out..fyi stock for stock u should notice better braking JUST upgrading to xt6 5 bolt hardware because of the bigger rear discs..I think the front is bigger as well but I have not had this confirmed.. I HIGHLY recommend anyone running 4 wheel disc brakes to upgrade to a 90-93 legacy 15/16th or 1" master cylinder for non ABS cars this is bolt in for ea82 cars. This will make your braking far more consistant and more progressive with effort and I find my car stops better in everyway..it will also put you in good stead for running fixed 4 and 2 pot calipers (the 1" MC anyway..) there is a 1 1/16" MC for abs cars but this will require additional hardware to bolt to the ea82 brake lines..
