I'm just going to blast some FRONT Koni "Race" PN Measurements here for future reference because who knows when this will disappear:
PART NUMBER | Adjustment | Diameter (mm) | Body Length (mm) | Stroke (mm) | Max Length (mm) | Min Length (mm) | Fitment |
8610-1436Race | SINGLE | 43.5 | 290 | 143 | 500 | 357 | iX |
8610-1437Race | SINGLE | 43.5 | 332 | 153 | 540 | 387 | RWD |
8611-1256Race | DOUBLE | 45.5 | 311 | 139 | 520 | 381 | iX? |
8611-1257Race | DOUBLE | 43.5 | 290 | 143 | 500 | 357 | iX |
8611-1258Race | DOUBLE | 43.5 | 391 | 158 | 615 | 457 | RWD? |
8611-1259Race | DOUBLE | 43.5 | 332 | 153 | 540 | 387 | RWD |
8641-1021Sport(E30) | SINGLE | 45.5 | 432 | 156 | 641 | 485 | Stock |
8641-1144Sport(E30iX) | SINGLE | 45.5 | 349 | 105 | 516 | 411 | Stock |
Stock E30/ix fitment values are not verified - I'm skeptical about the 325ix stroke, but the inserts are pretty short.
Still happy with the 8610-1437Race with 450lb front springs, 1" sectioned from the strut, ~2" spacer under the insert.
8611-1259Race would be a good option for people who need Double adjustment.
In the red:
This is the first I've seen for either of these but they might work really well?
The 1258 are only 41mm/1.6" shorter than stock RWD, so they could genuinely work well for a RWD car with 5" front coilover spring and no spacer.
The 1256 are only 30mm/1.2" shorter than stock iX, so could be good for iX guys to run without a spacer.
