Ok I have done a search for the last hour and still have not found the answer I need.

I want to know who has what springs/shocks and what size tires?

I have a set of 15" wheels (PS) and about ready to buy the Tokico blues with the RacingBeat springs.
Ok, so would I be able to run a 205-55-15 or could I run a 215-50-15?
Help!!!!!! My front shocks are stock (172k) and the rear
Illumina's are trying to keep the 225 50 15's off the wheel wells.

Does anyone make a set of good springs that keeps the car stock height?

 

I'm running 205-55R16s so not sure if 205-55R15s would give you the right rolling diameter...

 

Most times stock RX-7 springs are so sagged, that aftermarket "lowering" springs actually raise the car.

I remember when a buddy installed a set of brand new Mazda springs the other year, his car was so high it wasn't even funny lol. Brand new stiff shocks have a similar effect.

I don't think the RB springs are as low as you think, they're probably pretty close to where your car is now.

 

tire sizer:

 

Back when I ran a 80LS (SA22) in CSP class SCCA-SoloII, I was running Racing Beat springs and Tokico blues, ride height was reduced by about 3/4" front and rear, and 14x6 wheels. Tire size was altered between everything from 185/55/14 front, 195/55/14 rear which didn't work out well (balance), to what I settled on which was 205/60/14 all around. This resulted in rub at the front wheels during hard cornering, and also chopped the tire sidewalls from the metal rims on the insides of the fenders before I learned the trick to use a baseball bat to 'roll' the inner fenders to clear the rubber.

I currently drive an 84SE and have 14x5.5 wheels, running 205/60/14 AVS and these fit great. Same suspension from the racecar. No clearance problems, and the ride height is just about right. HTH,

 

Tanks for the input. I guess nobody is running 15" wheel on their 7 with after market shocks and springs.

What is really strange is the driver side front saggs more than the passenger side. I guess it is due to there is always a driver in it and hardly a passenger.

 

I have the exact setup you speak of, but my tire size is different. I am inclined to say a 205/55/15 would rub. 205/50/15 would be better. A 215/50 I am alomst certain would rub.

 

I'm running 205 55 15's and they don't rub, but I also have coilovers with camber/caster plates in front.

 

Felix Wankel and branca thanks for the input.

Currently I have 225 50 15 on the GSL-SE now with no rubbing until I hit the brakes or a bump then the front driver side rubs the top of the fender. The tires do not rub when I turn at all.
I really like the look of these tires but once I put new springs on the car I think it might rub alot. Someone said that my stock springs are so old (171k) that a new set of springs might raise the car.

Now i am thinking about Eibach springs, keep my rear Illuminias and get the front Illuminias.

Felix - Email me your exact setup. I know your car and can not afford the coilovers.

Here is a pic with the 225 50 15 tires minus the center caps on mine.

 

Another pic. The rear end showing the major meat on the wheels

I see why they don't rub when you turn! I think your car may actually raise up a little bit. Mine stayed about the same, it has 140K on it.

 

That sounds good. I would like to keep the tire that I have now. I guess I will know once I make up my mind and buy the setup I want. If it rubs then I guess I will go down to a 205. But I really like the 225 look.

 

Imho, 205's look better.

Do you know your offset and backspacing? Your setup looks just like mine, but I can't remember those two things.

I get asked a lot too.

 

i got mine used so i have an excuse :-P

I was never told. It was on the receipt, which I lost long ago.

 

What are your wheels? I like em.

 

I got mine used off eBay... and have no idea. I've been wondering what they hell they are too. Next time I have the wheels off I'll do the whole measuring routine to see if I can figure it out myself.

 

Yeah I was hoping to avoid having to do that myself

They do look awfully close.

 

Jeezus I really love those Panasports... almost makes me wanna forget about grad school and get a job.
