Rear Wheels Bottoming


Recommended Posts

Hey Guys. I'm getting the car road worthy and took it out for a test ride (not too legal but oh well icon_wink.gif ) Here are some of the things I found. The clutch is beat. I thought maybe it had air in it because it engaged really high. Nope, when you try and launch it hard the clutch slips then grabs after heating up. The other thing I found is that the right rear wheel was bottoming out. I have stock suspension in the car right now and the tire size is 215/70-14 on the turbine rims. The right is hitting the lip. It seems to happen when launching the car hard or cornering hard. I know you can role the lip, but how?? Do you guys a hammer and a 2x4 or what? Also, should the wheels be bottoming like that, or that a sign of shot springs and struts? It doesn't seem to bounce when you push on either side. Any help would be appreciated. Other than that the car is a blast. With the new tires it handles awsome and has very good acceleration for an engine with 175K. Thanks for the help in advance icon_biggrin.gif

Pete, there is some juicy info that we talked about (all the different ways of rolling the fenders). The most professional way is to probably get the fender rolling device that the Tire Rack (?) rents for about $35. Look up the old threads using the search function in this forum and in Body & Paint--you are sure to come up with the info! Good luck icon_smile.gif

Thanks for the info Davy. So how did you do it? I think I will call tire rack and rent the roller. It seems like the easiest to do. I'm still concerned, though, that the wheels should't be bottoming like that in the first place. Is that normal? 215 really isn't that wide but being a 70 I'm sure doesn't help. Thanks for the info guys.

stock 240? stock suspension? by now springs and shots are shot with 99% certainty. Does it drop an inch alone when you get in it? 215's on what width/offset rim? If zero offset they're going up quite high in your wheelwell and you're quite low IMO. 215's on a proper offset wheel may not IMO require rolling...225's will rub somewhat but right on the outer edge on a 16x7 zero offset. Naturally the actual widths vary b/t tire models by up to an inch b/t same spec'd sizes.

PETEW,

 

Some guys use gentle persuasion from a rubber hammer, but there is wisdom in renting a tool for that kind of thing--well worth the cost I listed above. If you rent the tool, you will understand how it is done. I don't know if there are instructions with ot or not??? Hey, I just realized that you can always check the web for "rolling fenders" or "rolled fenders" or rolling fender lips" etc. HTH

Thanks for all the helpful info guys. Fairlady, yes, I have a 280Z and it seems like it loves to squat. I haven't checked the wheels for offset yet, but they were popular with the Z's. They are the Western wheel Turbine wheels. They look ok on the car. New springs and struts are on order, but they will lower the car an inch, more cause for concern. I'll start the fenders this weekend, and let you know how they come out.

It could be done as well with a small T-dolly and a hammer (preferably rawhide or plastic, something non-maring). You would put the dolly under the lip and slowly work by slightly tapping the lip to slowly roll it up. Work around the fender lip all the way around. What I mean by that is, put the dolly in, slight tap, move it over a bit, slight tap all the way around it. When you get to the other end, you repeat.

 

The idea is to slowly roll it over, this isn't the time to just wail away with a hammer on it, you want to roll the metal a bit at a time, not just slam a hammer on there and bend a section where you want it and then move on, doing that produces a real uneven looking job with lots of kinks in it.

 

If the car has been painted recently, you may want to wait until its all cured and hard and then mask it with tape to keep it from being chipped. Better still, do it before you paint.

 

You can use the Baseball bat technique, to see that, look in our archives here at HybridZ (use the search function) as there was a long discussion (with a link to another site that shows the proces in pictures) about 'Rolling' the fender lip up.

 

Regards,
