I finally put the 597R HRE's on my '00 996 C2

 

okay, im scratching my head right now... I just bought this car. IS IT LOWERED??
the 285/30zr19 tire in the rear only has about 1 inch between the tire and fender

here is a close up of the rear, its a bad photo since i took it with the phone and its dark outside



And here one of the front (about 1.5" gap) they are 245/35zr19

 

LOOKS STOCK.... this is lowered..... nice wheels!!

 

ok the offset must be "wrong" on mine because if my car was lowered my fender would sit on the tire. "just slightly, but none the less it would still sit" what can be done??? or am i just S.O.L.??

 

There should be an HRE # on the inside of the wheels. Get the #'s and call HRE. They can tell you the details of the wheels (i.e. width, offset etc.). If the offsets are way off you might be able to send the wheels to HRE and have them swap a part in order to get the proper offset...

 

its those tires.... they are way wrong. You were better of with the 305/25-19. Now you are passed the 4% error rule of thumb. These cars were designed for 25" tires. Your performance threshold (ABS, PSM etc) has now been decreased....

Edit: looking back at your photo.... your rears are 285/30-19 not what you stated, 285/35-19 its seems you are good now (within the 4% limit). Then I believe it is your suspension.... pull out a wheel and take a pic of your shocks/coil setup and post it here.... if its a adjustable it shouldnt be a big deal to get it where it should be. Here is the new clac on the tires...

thanks redridge, but it looks like the issue is that my wheel/tire is flush with the fender so that if it does bottom out it looks like my fender will rub on the tire. And these are only 285's (heck 305's are with fedex on the way....lol)

 

i just pulled of the wheel and got the # so i'll call up HRE and see if they can help me out. The suspension IS STOCK!!!

 

I had 305/25-19's and they fit really nice.... its all in the offsets of the wheels...

 

redridge what offset do you have in the rears?

 

here is a top view over looking the fender


and one from the back

 

OK, i got of the phone With HRE and the wheels have a 43 offset. The outer lip is 3.0 and inner is 7.0 They are going to see what can be done to get 305/25zr19 tires to work properly, if possible. They can mill some material from the centers but usualy its only about 4mm if there is enough thickness. The other thing he mentioned that he is looking into is if increasing the rear lip will help pull the tire in a bit.

IM KEEPING MY FINGERS CROSSED AND HOPING THAT HRE CAN HELP ME WITH MY PROBLEM...

 

Have you considered rolling the fenders?

 

That will definatly be done, probably tommorow since its my day off

 

Sounds like it might take a lot of work to fit 305's. If not, you should be fine with the wheels/tires as is. The real issue is suspension (i.e. you need a way to lower and adjust negative camber). I suggest looking into coilovers.
