215/40/17 On Stock MP3 Racing Hart

[SKY]

Stock Tire Size for our MP3s are 205/45/17, I wonder if it's Okay to put 215/40/17 on our Racing Harts. Speedometer will be 2% faster which is OK, but I'm thinking about the low profile for the 40......and with my lowered suspension springs. (Eibach 1.4fr, 1.8rr)

Any thoughts?

I believe that the MP3's did come with a smaller sidewall than the MSP's did. You shouldn't have any problems with 215-45/17's. I am on Mazdaspeed B-spec springs and have had no issues.


Ty, I'm suprised you rub with the Racing Harts. I never have, before or after springs.

my car is just full of suprises. lol

Callie's actually rubs when we corner hard now, I have no clue what her offset is on the wheels she's running now.

Fender roller is going to be rented much sooner than i had planned now

I'd say so man. Do you know of anyone else having issues with MSP's rubbing?

 

[mx-p5]

nope. just me. go figure. and with stock suspension

Had an alignment lately? You may be pushing some positive camber in the rear that's causing it. As for Callie's, I would just guess an offset that could be a little much.

 

[mx-p5]

both cars only rub in the rear, mine when i have a load in the car, be it people or stuff, and hers is just an offset issue.

Fender roller and i think i'll be ok

 

[THE Phen]

Understood. I'm just trying to understand why yours is doing it.

Just in case it wasn't clear:

Stock MSP is 215/45/17
Stock MP3 is 205/45/17

Here's a tire height calculator I created if it's useful to anyone.
