The narrow body AX/race car I purchased last October has Boxster brakes up front and "m" front calipers mounted at the rear. I just ordered Rich Johnson's rear boxster kit for the 914 and will install it before the first AX this season up here... seems like a good idea to have a matched set of brakes that are engineered to work with each other. (I believe that the car is in E mod for the PCA AX, but honestly, I have no idea.) This is all well and good for AX, but places me in all kinds of weird and uncompetative classes in PCA, SCCA and is not legal for histerical classes.
I am not planning to race the car this season, but would like to go thru a few DE days and an SCCA drivers school in order to re-activate a 15 year lapsed license... Next year though, I would like to do a few historicals as well as an SCCA race or two. Anyway, now I have a good set of "M" fronts, a set of "M" rear (smaller piston size) calipers (rebuilt) and I was thinking...Hmmmm I could put together a complete set of front struts and rear trailing arms with these brakes and have a legal historical, SCCA and PCA system that I could just bolt on. Of course, I need shocks to match, but I have a set of front struts as well as trailing arms with elephant racing bearings installed - so this seems like a no brainer. Am I over thinking this? - I'm not out to win, been there done that...I'm out to have a really good time - so running in the other classes in an uncompetative car shouldn't really matter. Any advise from the peanut gallery? |

For that exorbitant amount of dead Presidents... yes, those would be the ones I didn't want. (IMG:style_emoticons/default/w00t.gif) (IMG:style_emoticons/default/tongue.gif)
The rear M's came in both configurations (early and late). You can put them together w/o the spacers and run solid. They bolt right on to a 914 at that point. Leave the 10mm spacer in and you can use the vented rotor but you'll have to either shim the caliper back 5mm or the rotor out 5mm. (IMG:style_emoticons/default/wink.gif) |
