AE86DC or rollaclub are your friends.... Mine has a very basic setup... ADM sprinter front end/brakes, TRD struts, AJPS springs, modded stock R32 struts and springs cut in half, LSD (locked standard diff) Corona Lower control arms (15mm wider track, 2.5 deg camber) and new bushing in the rear end. Could prolly have a similar setup for around $1k installed..... Buy a Keto for $500, you're ready to go.
Im changing the whole setup soon....
JDM twin pot calipers and vented rotors
AJPS front coilovers w/ Bilstein adj struts, 7kg springs, Cusco camber tops,
Bilstein rear struts and AJPS 5kg springs
AJPS 35mm RCA's
Whiteline front and rear swaybars
Noltec panhard rod
Cusco Tower bar and tension rods
AE86 power steering arms for more lock.
T18 diff locked
Not cheap (Bout $2800 - $3K all up) but it'll probably handle/slide better than my R31.... all it needs is a SR20DE in it and she's ready to go...
You can also fit an entire S13 front end, using RA40 celica/910 bluebird parts.... good if you can get S13 coilovers cheap 2nd hand....
they are essentially a AE86 without takumi tax.....
Oh, ordered my new wheels today... 17 x 9 and 18 x 9.5 drifteks in white for the 31, and 15 x 8 -4 superlights in platinum silver for the '70 .... gonna look hot.
