redline Rooster Posted August 19, 2002 Share Posted August 19, 2002 Hi, I have a UK TT and i'm looking to change the stock 17's for something a bit more yummy!! I want to go to 18" coz i've seen supras on 18 and they just look the bizz! Now i got a few things i need to make sure on! first my car has been lowered, only a little, and there is 15-20mm arch gap now, so basically i have to get wheels with the same offset (50mm i think) because if they stick out anymore, then over big bumps i'm gonna be doing some "on the move" arch re-modelling!! so is this offset right for the car. I've seen 50 on the alloys and assumed this is the offset. Secondly, the front wheels have quite a inward camber on them, and i replaced the front tyres a while ago as the inside treads where reduced to nylon!! - seeing as on 18's i'll need a lower profile tyre, does anyone know of this camber causing significant problems?! E.G more wear or worsened handling!! - if i have to stay at 17" so as not to ruin the handling i will! Cheers for any help!!!!!!!

Syed Shah Posted August 19, 2002 Share Posted August 19, 2002 I'm pretty sure it's the suspension that effects the camber rather than the wheels, and there is a spec to cure this. As for handling, not a problem really, 18" wheels aren't really pushing it on a Supra. As for offset, the bigger the better if you want them to fit 'round big brakes (UK specs etc), remember to get wide ones as Quote Link to comment Share on other sites More sharing options...
Bradb Posted August 19, 2002 Share Posted August 19, 2002 Redline if ya got UK spec 17's and wanna unload I may be ya man. PM me. Quote Link to comment Share on other sites More sharing options...
redline Rooster Posted August 19, 2002 Author Share Posted August 19, 2002 yeah thats right, it is the suspenstion thats causes the camber, because as you jack the car up, and the front wheels drop down, you can see the camber reducing. Its worse on mine because its lower then the factory levels. I cant really have a bigger offset as that means the tyres will hit the arches on servere bumps *as i found out with one of my other cars* I've got a UK spec so its got the bigger brakes on there I just really need to know if theres any problem with tyre scrubbing due to the camber they're at seeing as i do use the car alot, i dont want to be going thru front tyres every couple of months!! hahaha Cheers for the info!!

Syed Shah Posted August 20, 2002 Share Posted August 20, 2002 Oh, if you have Uk-spec brakes you are going to have to make sure whatever wheels you get fit round the brakes, as this can be a problem and will limit your choice, if needed, get the arches rolled to accomadate this.

DArby Posted August 20, 2002 Share Posted August 20, 2002 Red. Go get a full geometry check. They can set camber and caster to remove scrubbing problems and set everything back within correct operating parameters. Dean. Quote Link to comment Share on other sites More sharing options...
redline Rooster Posted August 20, 2002 Author Share Posted August 20, 2002 hmmmmm yeah a geometry check isn't a bad idea actually, its in for a service at the end of the week and the place has all that gear so i'll get to make sure all is OK. Archrolling - that did cross my mind that i might have to do that!!! ouch, I've seen too many examples of where this has gone wrong to go down that avenue!! ahaha, i'm sures its fine as long as its properly treated and sealed after its done! - well i'll have a look round and get some ideas together! cheers for the help guys!!

Need4Speed Posted August 20, 2002 Share Posted August 20, 2002 I've got my camber set at -0.5 degrees and the car turns in well and is neutral with the usual power oversteer (tyres are 275/35 series rear and 235/40 series front 17"). I don't know what your car has in the way of suspension, but I assume the camber is adjustable on the standard car (and the castor aswell). Take it to someone who knows about set-ups rather than some place that does wheel alignment. The correct camber for a non standard car can only be found with testing and tyre temperatures, or even how you like it to handle (feel). Camber and castor are simple to set provided you have the right kit - it's not rocket science and you don't need expensive equipment with lasers etc. (you can track a car with a ball of string and a ruler!) I'm sure one of the established names on this BBS will be able to help. Quote Link to comment Share on other sites More sharing options...

It really is quite useful Quote Link to comment Share on other sites More sharing options...
redline Rooster Posted August 21, 2002 Author Share Posted August 21, 2002 Cheers Thorin!! Thats spread sheets excellent!!! - yup i definatly reckon that should be put back up on the forum cool! Rooster :flame Dev Quote Link to comment Share on other sites More sharing options...
