Thanks for the help.
Ok I run a 79 nova with white spoke wheels and grand am tires. This season the track will start allowing (asphalt) tires. The wife has agreed to go ahead and buy 4 light weight rims to mount these on. My question is about offset on rims? I've read about certain rims being set to inside and some to outside. any help on ordering will be nice- like the proper offset for rf lf rr lr. The rims I'll be ordering are 19 lbs probably 7-8 lbs lighter per wheel so Maybe I'll be able to tell a difference. And she approved a set of cheap headers

This is a statement to think about If you run L/W rims on a streetstock you may have trouble bcause of the repetition of stress on the center section of the wheel know this isn't what you want to hear but I just thought someone should say it As far as the offsets go you need diff offsets to do diff things you tighten your car with offsets you can loosen your car with offsets I don think its a cut and dry answer myself when I started out I ran a 2" offset all the way around and experienced with diff offsets on diff wheels for instance I could loosen my car up by using more offset on the rt front or tighten it up by more offset on one side front and rearI think the moral of my story is talk to other racers where you race and see what kind of luck they've had with L/W wheels Versus Standard weight wheels and see if the price diff is justified and see how they work their offsets most racers are glad to help you Sorry this thing is so long

I believe I've seen bart wheels out there. the wheels I'm thinking of buying are basset wheels. As for the offset- The rims go by backspacing when ordering. 2" 3" 4" and so on. What is a Standard backspacing?

most lightweight wheels have the thick center and just the shell is lightweight. i think the shells are .098 thick compared to .135 or more for a regular weight wheel.

if you're just starting out, use the heavier wheels. you'll go broke keeping lightweight wheels on the car if you're hitting everything on the track. lightweight wheels will "egg shape" easily too.

if you have some experience and are careful not to "beat-n-bang" with 'em, then lightweight wheels are the only way to go. my opinion......

I've run Diamond wheels for years on heavy street stockers, no problems except for bending one here and there rubbin fenders. They do have re-inforced centers. I'd rather bend wheels than suspension pieces.

there is no real true answer to what you need you will have to put the car on some scales or run it for a while to know exactly what offsets you need. i use aroe wheels best around in my opinion and better looks than most i got 15x7 with the sivler powdercoat wheels off pitstopusa.com they only list the black but if you requset the silver they can get them for a couple bucks more. everyplace is different when ordering they sell there as back space meaning the mesurement from the inside of the wheel to the mounting point

No ones really biting on your true question so I will give it a go ALONG with my advice. You really don't want to buy the light wieght wheels. They will get messed up way too fast. Aftermarket wheels are a good idea however. On the right front I would run a 2" off. For some reason my cars always liked the front stance wide, I know there is a reason but I am not sure if I wanna try to quote anyone. Get 3" for the left front. I would then buy a 2" and a 3" for the rear. On a sloppy wet track run the 2" on the right, and the 3" on the left. Come feature time (provided that your track is dryslick now) your gonna wanna switch the rear wheels around to help with tightening the car up some. If your track is still tacky just leave them alone. This is assuming that you don't run stagger, that would really alter things Your wagon(white spoke) wheels should be a nuetral offset ie 3.5 on a 7", 4" on a 8". I hope that I have been helpful, even if I have given you an answer you dont want.

THANKS !!! A ton of help. I'll be writing some of this down. But I may still try lightweights at least on rear maybe street tires on front and asphalt pull offs on rear with light rims. Thanks again for the input.

I've tried running the white spoke wheels on my car several times and they never last more than four or five nights. They start cracking in the centers around the studs. Fortunately I've always caught them before the whole center breaks out. I've never had cracking problems with racing wheels. Everyone will have an oppinion but mine is to use racing wheels if the budget allows.

absolutely but I think the main point most of us were making is not to start out using light weight rims because you will abuse them and they will fail as all rims will fail but a LW will fail much quicker

Yes, lightweight rims bend easier. But, I can buy a $60 rim faster than a $200 stub.

We're talking about a pure street full frame car here and not a snout car I assume ?

how big are these pull off tires if they are wider than 8 inches i wouldn't advise running them on the rear only you want the front track of your car wider than the rear if possible.
flatlander a full frame stub bends just as ez as any other type of frame been there done that lol

Maybe but I don't redo them I replace them and as a full frame car usaully has a steel body to help protect it and the speeds are slower you're not as apt to destroy it IMO

get all my wheels from summit only, they will ship as many as your order for 7.95....you cnat beat that i ordered 20 once and had them coming for weeks,lol. all for one fee of 7.95..

they even have imca 8 in wheels,

i allways buy lw. ive never busted one or cracked one, and i have some 8 years old...
i have had them fold up around the wheels studs in a wreck before and not bent the axle or anything else, a stiffer wheel would have ruined more than the wheel.

granted they are hard to get bent away from the studs in a hurry, at least it appeared so from my drivers seat as my pit guys were sledging away to get me back out... but after bending it out i went on to race.

I have both I like the light weights but as everybody said they bend easier but this helps from destroying other parts if you can keep the other people from ramming you.I went through a lot of 19 lb rims.I use aero rims.One thing nobody mentioned was on offset,you better see if your track has any tread width rules.My track has a 75" max which a 2" ofset all the way around works for me and I can move tire position for stagger easier with the same offset.My car handles good most of the time with out changing offset.I got rammed in left rear tire with a light weight rim on by someone doing 60--80 mph broadside and it bent the rim and the axle flange but not the housing a 10 minute fix instead of 3 hours .This is a 9" ford.With the way gm axles are made a lw would be a wise choice to lessen the damage on a rim impact.
