mattdavies Posted July 16, 2015 Share Posted July 16, 2015 question is what ET do i need , i would like a little poke but im not looking at any arch modifications (standard body) If you look in the rear wheel arch there is a large lip, you wont be able to get 'poke' without rolling the arch !!

supramat Posted July 16, 2015 Author Share Posted July 16, 2015 didnt realise about the lip, id like them to sit flush , as my current wheels look awful as they sit in the arches Quote Link to comment Share on other sites More sharing options...
Nic Posted July 16, 2015 Share Posted July 16, 2015 (edited) An offset of between 35 & 40, front and rear should give you what you want. edit: Just looked at the website, +33 would be the best offset to go for but you'll probably need to get the wheel arches rolled to stop the tyres rubbing. If you have the larger Supra brakes fitted, you'll need to make sure the wheels will clear the calipers.

Im still a bit confused , think im goona have to get the arches rolled These are mine, they are 18x9 +32 (245/40R18) & 18x10 +32 (285/35R18), the wheel arches needed rolling to stop the tyres catching. More pics in my garage HERE. If you go with the guys recommendations, compared to mine the +30 fronts would stick out an extra 3mm and the +20 rears would stick out an extra 12mm. The JR-12 wheels look like they have quite a deep dish, if you have the larger brakes fitted you'll need to make sure there is enough clearance between the front face of the brake caliper and the back of the spokes.

supra_ufo Posted July 16, 2015 Share Posted July 16, 2015 I have had some bad experience with JDM Distro its in my build thread in my signature. Japshop are the official UK distributor of them. JDM Distro are an Irish company I believe. I bought a set of JR11, they had 8.5-11inch sizes, most of which were crazy offsets. Based on my current 18s, 9.5 front ET35 would be perfect however mine because of the wheel design fudge my big brake (UK brakes) even with the 19s I selected. IF your jspec your laughing but the JR12 are not concave so no need to worry.. This is your chart for your wheels So based on these you only have 9" and 10" available personally I would go for 9" with ET30 fronts 10" ET25 for the rears Both would sit flush and have a very slight poke by my calculations Quote Link to comment Share on other sites More sharing options...
