Disc brake rear end vs Drum brake

[daz86]

just wondering about jdm rear diff thinking of buying one for lsd but i heard the disc brake were not as good as drum brake. anyone shed some light

and what would u roghly pay for one

[mikes86]

jdm rear= min 1g
t18= 200ish

[daz86]

yeh i have a t-18 with 4:1 ratio locked diff but i want to go lsd as i use my car for a daily driver as well and i only have 1 point on my license so i dont want any more attension from police

Depends what ur using it for... disc brakes would be better on the track... for drifting... drums would make the hand brake action stronger and more bite... but if ur not gonna use hand brake to drift... the disk setup with a brake bias valve will make ur car easier to setup brake bias wise.... very easy to make a car oversterry under brakes with brakebias valve.... never tred with drums so cant comment (it may or may not work)... each have their advantage...
Overall...its hard to argue that drums are better than discs in my opinion... but the cost is a big issue here.... JDM disc rear ends are bullshit expensive nowdays... The disc conversions people are talking about might be the best bet.....

P.S. i can yank on my handbrake with the disc setup and it'll lock semi slicks at pretty much anyspeed in a straight line... even easier if the car was unbalanced... A lot of is to do with the pads ur using and how well setup the handbrake is... took a lot of stuffin arround to get everything true/straight and accurate...but the results is fantastic!!

Keep current diff setup and purchase a 1, 1.5 or 2 way LSD.

A brand new mechanical lsd will serve you very well and will cost around the price of a JDM lsd disk brake rear...with an unknown condition 2nd hand lsd.

cool thanks for the info where would i get a 2 way lsd alot of new ones i found were around the 1200+ mark thats why i was thinking of going a disc brake with lsd already

[crazy86]

weather you go JDM disk or T18 drum, or any other T series rear, you still have to buy the same LSD, same cost etc. No difference. If you buy a JDM rear with an LSD, its either a stock LSD or a second hand aftermarket (TRD/Cusco etc). You can also get the same stuff in a T18 diff, no difference.

Secondhand LSD? I've got one and its only good for a few weeks. Should have bought a new one instead http://www.ae86drivingclub.com.au/forums/emoticons/sad.gif

One advantage of a disc rear end is they usally come with 4.3 which is good.

true you MAY get an LSD in the disc brake setup.. MAY.. but you would prolly need to rebuild it anyway.. stick with the T-18.. if you were to take your drum linings to a truck brakes place they will rebond them with some commercial type bondings which bite a shit load harder, and resist the fade.. i think the only real huge advantage over drums is discs can disperse the heat a million times better.. the brake bias valve should work.. same principal!? how bout you just get me a freebee Jack and will try it on mine.. http://www.ae86drivingclub.com.au/forums/emoticons/ph34r.gif hope he falls for it..opps shoudln't have typed that bit..

[Medwin_3sGTE_AE86]

haha... yeah... i'll rip mine so i dont have rear brakes and put bubbles in my $50 worth of fluid...
but yeah... anyways... the only reason i have doubt is because even when u tighten (most... ie. willwood,tilton) brake bias valve to the limit... its still not completely stopping all the fluid (maybe reduce pressure by 60% etc..).... and wheel cylinders for drums run a fraction of the pressure of disc calipers.... thats why i say maybe.....

i dont know why disc rear ends are so pricey...i got mine straight from japan for 550 bucks...no lsd mind you...and its needs abit of love...but i pulled it apart and bearings are 100% and shafts look friggen new http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

[mattysshop]

This is case of demand vs supply where theres more of a need to buy it than a need to sell it.

And your lucky, after my welded diff died the cheapest I found was 2g's (zenki cusco lsd)

[crazy86]

Its possible to find a good price, My JDM disk rear was 1000 with a TRD 2 way

[monkeymajik]

I've got a rebuilt t-18 with a KAAZ and 4.1 gears.

If in the future I wanted to go disc brake. Would it be cheaper to adapt disc brakes to my t-18 or go for a JDM T-series?
