Jetpilot Posted January 18, 2015 Share Posted January 18, 2015 Doesnt work like that, 18, 19 or 20's etc will have or should have the same rolling radius as you compensate with tyre profiles to keep same diameter. You will not fill the arch more if you have the correct profile tyres, only way to reduce arch gap is lowering. Quote Link to comment Share on other sites More sharing options...

Correct, but i was implying that the rolling radius would need to be bigger to pull this off. its a tough one really. but what i really need to do is to put my hand in my pocket and get some hydraulic suspension with quick pre-sets :lol: speed bumps = not an issue. looking like i have a car full of 25-stone men in tescos carpark = not an issue.

Jetpilot Posted January 19, 2015 Share Posted January 19, 2015 It would then look like your runing 4 x 4 wheels and tyres. Just avoid routes with speed humps and the places it scrapes Quote Link to comment Share on other sites More sharing options...
Pritchard Posted January 19, 2015 Author Share Posted January 19, 2015 Just found a 370Z for sale in the US running 20" Vossen CVTs. oooo want I want. I feel like a horny teenager with a Nuts Mag when i see these. Concave-ness too :D Quote Link to comment Share on other sites More sharing options...
docwra Posted January 19, 2015 Share Posted January 19, 2015 (edited) Mate, theres no point spending thousands on a sweet bodykit and wheels and then running 4x4 ride height, it will look pants. My car is lowwww, but its still driveable 99% of places Edited January 19, 2015 by docwra Quote Link to comment Share on other sites More sharing options...
Pritchard Posted January 19, 2015 Author Share Posted January 19, 2015 (edited) where has 4x4 come from? and why is it being repeated? well, unfortunately i dont have a 99% luxury here. in fact, getting off my driveway would be the first stumbling block.

docwra Posted January 19, 2015 Share Posted January 19, 2015 With all due respect, if you arent prepared/arent able to lower the car you may as well save your money on the kit and wheels, it will just look half arsed otherwise 3 days after moving into my house we had the driveway relaid so we could get the cars up it, this was considerably preferable to making them look like they were on stilts Seriously though, you might not think it will make a lot of difference but it really, really, does particularly when a car is kitted and wheeled Quote Link to comment Share on other sites More sharing options...
Pritchard Posted January 19, 2015 Author Share Posted January 19, 2015 (edited) I appreciate that. there is going to have to be compromise somewhere. when the car comes back, and wheels get fitted i will then measure my clearance over the drive, and over some local bumps. and take it from there. i am not expecting to have alot to play with though, if anything.

Jetpilot Posted January 19, 2015 Share Posted January 19, 2015 (edited) where has 4x4 come from? and why is it being repeated? Because thats what it will look like running high profile tyres by trying to fill your arch gap, it will also most likely play havoc with your tcs if dont keep the rolling radius very near the same. If you need a compromise Tein springs offer a slight drop Edited January 19, 2015 by Jetpilot Quote Link to comment Share on other sites More sharing options...

If you need a compromise Tein springs offer a slight drop Right, i see what you mean now. i think ''4x4'' is a bit over exaggerated in my head i was thinking of mm's in the single figures to help the clearance issue. I wasnt looking for arch gaps like this, nor do i intend to partake in this awesome looking activity. Quote Link to comment Share on other sites More sharing options...

Jetpilot Posted January 19, 2015 Share Posted January 19, 2015 Personally i dont think you will see a noticeable difference with mm's of extra profile, 10mm/20mm is neither here nor there over the entire radius, your talking 5mm or 10mm of arch gap filled (let alone tcs issues) I am with Docwra, an awesome bodykit and decent rims will be lost if your riding high as per Grundys post. Good luck with the project Quote Link to comment Share on other sites More sharing options...
docwra Posted January 19, 2015 Share Posted January 19, 2015 4x4 might be a bit of an exaggeration, as is the old "family of immigrants living in your arches" but any visible gap at all will severely detract from the look of the car. I can only use my car as an example - this: looks a lot better than this: and the only difference is the arch gaps. 2 Quote Link to comment Share on other sites More sharing options...
Pritchard Posted January 19, 2015 Author Share Posted January 19, 2015 Monster truck family This is what they mean by 4x4 stance yes this! this is what i mean by raising the ground clearance with bigger wheels, BUT then lowering onto the wheels. in doing so the arch gap can be reduced over OEM, without suffering a ground clearance loss over OEM. (give or take some mm's) Am i just not explaining this right? Quote Link to comment Share on other sites More sharing options...

You wont change the ground clearance with bigger wheels though, the only way to change the ground clearance is to run bigger profile tyres (change the rolling radius) and then you will have nasty fat balloon tyres like a van or 4 x 4, which will then make your expensive alloys look sh*t.

Grundy Posted January 19, 2015 Share Posted January 19, 2015 Just FYI GrahaM's zed in that picture had just had them fitted. So suspension hadn't settled #teamtarmac Quote Link to comment Share on other sites More sharing options...
Jetpilot Posted January 19, 2015 Share Posted January 19, 2015 (edited) For example, most people run a 275/35/19 the next profile up is 275/40/19, thats an extra 25mm give or take, so you have raised your ride height 12.5mm and filled your arch gap 12.5mmm (tcs issues again which you dont seem to want to acknowledge), hardly noticeable anyway in my opinion, if 1cm ish is all your have to play with i suggest. 1) Give up 2) Get air 3) Avoid the areas you know you cant go Edited January 19, 2015 by Jetpilot Quote Link to comment Share on other sites More sharing options...
Pritchard Posted January 19, 2015 Author Share Posted January 19, 2015 I am absolutely positive that i have just worded this wrong from the start, or its been mis-read and now we are counter-arguing specifics. lol. so clean page. Using rear wheel as the example: Current size: 245/40/18 expected new size: 255/35/19 That change raises the car by 4mm off the ground. allowing me to lower the car back onto the wheels by 4mm without loss of clearance. Rolling radius change is -1.2% And the tyre profile is not ballooned. Or, 245/40/18, to 245/40/19 will raise the car by 12mm, allowing for a more substantial drop (and probably arch rolling). the former is my more likely option. *Just seen the email update while typing this about the 275/35/19 profile to 275/40/19 ... whaat? lol. i am on OEM wheels!

Jetpilot Posted January 19, 2015 Share Posted January 19, 2015 You worded it right, everyone knows what your talking about but: You do know how big (more so small) a mm is right. 4mm is immaterial, 12mm barely noticeable, not to mention the issues with tcs again if you go almost 4% out Will leave you to it Quote Link to comment Share on other sites More sharing options...

BulletMagnet Posted January 21, 2015 Share Posted January 21, 2015 Just bite the bullet and get airride suspension, as low or high as you want when needed, done Quote Link to comment Share on other sites More sharing options...
