Thomasjones Posted February 3, 2020 Share Posted February 3, 2020 Hi, I’m currently adding a Ridox body kit to my Supra and was told I may need to get 19 inch wheels.... can anyone comment on if this is accurate. Thanks Tom Quote Link to comment Share on other sites More sharing options...
evinX Posted February 3, 2020 Share Posted February 3, 2020 Need the width and offset to fill the arch properly to. 18s would work to. 17s may look diddy Quote Link to comment Share on other sites More sharing options...
ShawnPreece Posted February 4, 2020 Share Posted February 4, 2020 Hi mate im full ridox kit and info on my set up is here on pages 11 & 12 I did also write a guide up a while ago of how to work it all out but had a quick search and cant seem to find the thread for it, will have another look for it if you require Quote Link to comment Share on other sites More sharing options...
Thomasjones Posted February 8, 2020 Author Share Posted February 8, 2020 Thanks for the link! I’ve decided I’m going to run 18s front and 19s rear (mainly because I don’t want to buy 4 wheels) and just to get a bit more ground clearance.... There’s nothing wrong with doing this is there?

Frank Bullitt Posted February 8, 2020 Share Posted February 8, 2020 Frank Bullit, do elaborate All you need to know is in my answer to your question. Yes there is everything wrong with doing that unless you want to find yourself and your Supra sitting in a ditch or worse. Quote Link to comment Share on other sites More sharing options...
Thomasjones Posted February 9, 2020 Author Share Posted February 9, 2020 Look I appreciate you commenting but unless you provide back up to why it’s just an opinion. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 9, 2020 Share Posted February 9, 2020 Changing wheel size to give a desired ground clearance is very how you dooin', that is a really horrible way to go about it. Is the increase in ride height needed for ground clearance reasons or wheel arch to tyre fouling issues? Post some photos before you create a ditch finder mongrel.

Mo Reviews Posted February 9, 2020 Share Posted February 9, 2020 Physics isn't really an opinion. The bigger the wheel, the smaller the side wall. The smaller the side wall, the less flex you have in the tyre when accelerating. The less flex you have in the tyres, the less grip you have. The less grip you have, the more likely you will find yourself in a ditch. Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted February 9, 2020 Share Posted February 9, 2020 It would seem the OP has already found that out Before Christmas I spun it off the road but drove it away Quote Link to comment Share on other sites More sharing options...

Keep up guy's, nineteen's were in last year, twenties are now Officially where it's at, as seen on T.V. Every idiot knows that since 2017, a trendy Supra's wheel size should match the last 2 numbers of the year! Look out 2024?

Noz Posted February 9, 2020 Share Posted February 9, 2020 If you want ground clearance. Get coilovers or get air cups for your suspension. Quote Link to comment Share on other sites More sharing options...
David P Posted February 9, 2020 Share Posted February 9, 2020 (edited) If you want ground clearance. Get coilovers or get air cups for your suspension. Say's trendy Mr 19's in 2019. P.S. What do you do if you want traction? Edited February 9, 2020 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 9, 2020 Share Posted February 9, 2020 No issues with 19's on my last mkiv which were on for 8 years whilst i owned the car Quote Link to comment Share on other sites More sharing options...
Noz Posted February 9, 2020 Share Posted February 9, 2020 (edited) I thought the issue was the mismatch of wheels. David. With my 325 R888 I now get traction okay unless I launch it. I would personally only put 19s on a car if you can get a 12J at least. For the reasons listed above. Get that sidewall wrong and it's dangerous ground. I mean I had run flat Michelins pilot sports and the stiff sidewall made the wheels spin at 80mph on WOT on full boost (even on low setting). R888 have a really soft side wall but I'm sure the compound they are made from also play the major role in their grip. I'd hate to think what any Supra would be like on 19s with say a 265-285 width and a stiff side wall.

Frank Bullitt Posted February 9, 2020 Share Posted February 9, 2020 I thought the issue was the mismatch of wheels. Partly is mate. Order of preference for drivability and handling would be the stock (f)17"/®17" then (f)18"/®17" and lastly (f)18"/®18".The latter of the three being most effective on a 40 profile front and back. The the reverse hotrod idea on a RWD car Wanting to run 18" on the front and 19" on the rear because you don't want to buy four wheels the same size and want a more ground clearance. Madder than a bag full of badgers. Quote Link to comment Share on other sites More sharing options...
