I took a different approach: I run 305/30-19 MPSS all around on my R-spec SV501s.
Slightly more stretch in back vs. the stock 315 Cups
Slightly less stretch in front vs. the stock 305 Cups
This is because the MPSS (and the MP4S) have more of a square section profile and slightly wider tread...
Just to close this out, I ended up going out of pocket but getting the parts online (Tasca). $35 but it saved a trip to the dealer and the headache of explaining what they did wrong, and the splitter is 100% correctly attached now and rock solid.
Time is money. If it were $100, it would be worth the trip to the dealer and the fight. For $35, just not worth the hassle. I hear you on the principle, though. I'm pissed off about it and will be even more reluctant to let the dealer touch the car in the future.
Thanks. Was hoping to avoid waiting for shipping, but the local dealer (who probably threw away the original hardware) wanted $75 for all of it. Was able to get it online for about half that.
In other news, got the Caliperfexion studs installed today (finally!). And the oil is changed and the...
I removed the splitter from my R this weekend to install a front tow hook solutions (went with the ZL1 Addons to avoid modifying the grille).
I was upset to find that the dealer left off several fasteners when installing the splitter:
- the 4 black screws that go up into the splitter at a 45*...
Huh, at least just measuring on my screen the R does appear to be narrower than the other characters.
More broadly, I guess I question why? Is it for people who need to be sure everyone knows their R is an R?
If one looks at the long-term history of virtually any limited-production performance car, you'll see the same thing. Limited short-term depreciation, moderate mid-term depreciation, long-term appreciation. A few examples:
1) Porsche 911 turbo. Pick ANY generation. Expensive cars, hold value...
Scanning completed auctions on Ebay shows that most Rs (even used ones) are still being bid up to $70-80k. Not sure why dealers would be selling new Rs for MSRP when used Rs are bringing MSRP+ on the auction block. I do note that a lot of these are not selling, which means sellers are holding...
Nice that they make it R-specific with the red stitching. If one were to only put a child seat back there, what would be the issue with only installing seat belt receptacles and notching the seat delete panel vs. installing the full seat? The LATCH anchors are still in place from the factory...
I'd be interested in knowing this, too. Given what Ford pays Multimatic for those wings, they must work because it's a meaningful percentage of the Base/R price delta (if rumors are to be believed). In fact, considering the R-specific development costs for DSC, ABS, and the aero, as well as the...
