Spacers give you a wider stance and is mainly for aesthetics. In most cases handling can be adversely affected because of the increases scrub radius and reduced spring rate effectiveness at the wheel which more than likely cancels out any traction benefits from being 20-30mm wider. I found that I did not like how spacers affected my F80 handling characteristics. They look great and make a big difference in the aesthetics and enjoyment of the car in that department but ideally, they should be run on the street and removed for high performance driving on a track. They are also restricted on some track days which should tell you something.

I have a 320 sport line... I don't track or race and I am not looking for performance. Will it affect the handling at a point where I don't like to drive my car and feel it doesn't turn right or something? |

I had it on my F80 for canyon runs and did 77 laps at Willow Springs... while it wasn't as sharp with it, it was still very fun and driveable. Granted, I had aftermarket suspension which was slightly stiffer.

I have these tires and they are "ok". They have a little bit of a squishy feeling to them. I got used to them now after a year or so so I'm not noticing it as much. The ride IS smooth, the grip is decent (but not better than more expensive products). |

I've had them for a couple years now on my supercharged 350Z, they're decent, especially for the price. Pretty progressive and audible on breakaway. They're basically the next generation of the Bridgestone RE760, which was a pretty good tire in itself. For the price, they're a pretty good consumable for track days. Not as sticky as the more expensive rubber, but they'll take a beating and last a while if you're not racing a clock.

When i got my PS4S installed at Costco a couple of weeks ago, they called me right after they pulled the car in and asked me if i knew i was installing non RFTs in place of RFT. Of course i said yes (that's the point, lol) and they acted like i was crazy saying that i don't have a spare and would have to get the car towed if i got a flat, but they still proceeded with the install without a hassle. |

I'm hoping a couple local independent shops won't have any issues. If nothing else I'm pretty sure the speed shop which sponsors our local SCCA autocross events will do any tire work I need, but they are an hour drive away.

There were numerous options for different load rating, speed rating, etc, even within the same exact tire size. FWIW, i went from runflat to non-runflat and i also went to a non-OEM size (changed fronts from 225/40/19 to 245/35/19) and Costco installed them without issue. I think i went to a higher speed rating and load rating. |

Now back to the tires, I have them on two of my cars. They are more than fine for my GT. Ride quality and handling are both fine for what i do with the car. The price is real nice. On my other car, i will be getting something a bit more sticky as i break traction 1-3 with them. not worried about 1-2, thats going to happen but I want something that hangs on a bit more in 3rd. |

Remember to ask about the friends and family discount. It's been worth 15% a few times for me.

I'd like to update my response to this. The adverse effects of spacers are minimal with reasonable widths. What will affect handling is changing the ratio of track width front to rear. You can change grip rotational characteristics this way. This is mostly for those who track their car and are going for PB lap times.

I am now starting to think about whether or not there will be any issues with the TPMS. I guess I'll find out on Monday. Have a nice weekend. |

1. The tire seal/plug kit. BMW M cars come with one OEM. 2. BMW OEM space saver spare, which fits over M brakes. IIRC it was around $350 (tire and wheel) What are you worried about with TPMS? As far as i know mine were reused between my RFT and my PS4S when they were changed. Changing the tires should not affect the TPMS, unless you were saying you were concerned about what happens if you get a flat on a non RFT? Last edited by thejeremyman9; 02-24-2020 at 12:30 PM.. |
