Hmm.. I think it might eventually get an R-spec but the probability isn't that high.
I don't see them ever doing a rear indy setup for the suspension and without that, calling it an 'r-spec' would be kind of silly as the torsion does have its limits..
Regardless of that, there is no 'track' model of the Veloster like there is the Gcoupe and I am not quite sure what all they could do to make an R-spec model to differentiate between base and ultimate.
Of course the R-spec would be based off of the base model (118lbs lighter) but I don't see a very big point for bigger brakes since 12" rotors and the beefy front calipers should do very well.
I doubt they would do a power jump in a R-spec version, as they don't on the Gcoupe.
IF they do an R-spec on this car, I think it will be more of a novelty than anything higher performing like the Gcoupe.
Some things I would like to see in a Rspec:
manual front cloth seats (lighter/cheaper)
upgraded pads and dimpled/slotted rotors (better stopping and less fade racing)
Limited Slip Differential (better in the corners)
Summer 'Performance' Tires (225/40/18)
tuned suspension (not necessarily much stiffer, but tuned for the corners better)
R-spec badges
few unique colors (electrolyte green, Marmalade, Copper)
tuned exhaust note
Re-designed wheels with a bit less of an offset (42 vs. 49) or 18x8" that are a bit sportier and somewhat lighter.
All of this, priced slightly under the Ultimate package, based on the Base model seems like it would be a good, realistic R-spec car without getting to crazy by adding power or tuning it (killing economy or reliability)
With the LSD, suspension and tires, the car would be MUCH better in the corners and at the track.
The upgraded (but not Brembo) rotors/pads would make it much better for aggressive racing on a track.
Black Cloth with red trim and manually adjustable seats are back to the basics while saving on money and weight. Replace the TURBO with R-spec.
Throwing in R-spec only US colors would set it apart from a regular VTurbo even more.
Using badges similar to the Gen Coupe wing badges but like V R-spec would add to the flair of the car.
The car would probably accelerate faster with all of these mods due to losing a few pounds and having respectable tires from the factory and most definitely would handle better with the tires, wider track and wider profile (225)
