Need a little help with offset and clearance issues with coilovers.

[JDMbyBlood]

Whats up guys. Need some help from you offset experts. Im still in the process of doing a 5 lug conversion on my 93 s13 Coupe. In the meantime I picked up wheels, tires and a set of Tein Flex coilovers. I should have done a little more research before buying them, but after doing a quick search, I've seen people put some CRAZY offsets on there car. Here is what Im working with:Rays Eng. Gram Lights 57F *Front:18x8.5 +30 Off Set *Rear:18x9.5 +20 Off Set Dunlop Tires *Front: 225/40/18 *Rear: 255/35/18Tein Coilovers *FlexMy questions are:1. Will the front wheels fit without problems with the Flex Coilovers??2. What kind of rear fender pull will I need for the rear wheels to sit flush with the fenders?? Can I get away with a slight pull, or Im I going to need a good fender pull to get them to sit flush?3. Last question, can you do a front fender pull? I've never heard of anyone doing one, but thought I would ask you guys. I've always liked the look of the wheels and tires flush with the fenders. I was able to get a great deal on the wheel and tire package and I hope I didnt make a mistake in buying them. Thanks for any help you can provide/suggest**Note** If any of you dont mind, please post a pic of your fender pull. Just want to get an idea what mine may look like. Thanks again....

1) sure. Pretty much all popular coilovers have the same clearance, with maybe a difference of 5mm

2) put your wheels on first, then find out if you need a pull or not. It really depends on your camber and if you want a tire stretch... but with the tire size you provided, you may need a slight pull... for example

this is what a 10" with an offset of +18 (similar to that of your 9.5 +20)

as you can see, because of his stretch, a crazy pull isn't necessary. I guess that's really up to you if you consider a stretch. The pic I provided is with a 235/40/17

3) Dude... with the wheel and tire choice you provided, you won't even have to worry with a pull... you should consider a lower offset, especially since the wheel width is smaller. Just make sure you check with the manufacturer specs that the desired lower offset still allows caliper clearance...

I'd say for the fronts, go with like a +20 or less (personally, I think a +15 with a mild stretch and ever so slight camber is perfect), and depending on camber chosen, you may not have to need a front pull...

but, regarding you front fenderpull question, I don't think its possible to roll it like you'd do with the rears, cuz the whole damn fender moves and flexes with the roller! lol seriously tho, its easier to get an thinner roll if you take the fender off and do it on the grass or something... that's what I did... it allowed at least like a 10-15mm clearance... hell, I rolled my cousin's front fenders with a hammer, lol... it worked out well too

18x9.5 +20 all around... not too many good pics at the moment. Tad of camber

^^ cool. You should probably also post up your tire specs too

[smocan]

my bad... 225/40/18 federals all around... And feds seem to be a tad wider than other brands, others would stretch tad more, dont ask why but the sidewall is quite stiff... But it seemed when i looked at other 9.5s with a 225/40, the stretch was greater with tires other than feds, i may be wrong though

And for the record, 9.5 +20 in the front clears my coils by about 1-2mm... real close

heres when they were new...

^ yeah, federals have a pretty beefy sidewall. My buddy had to pull his fenders like a few mm's more when he first got his federal 595's. They were rubbing when he first put them on, compared to his previous tire stance.
