1.8 rotors/pads on rear of 1.6
 

I have in my grubby hands a complete set of 1.8l rotors, pads, brackets and was considering doing the 1.8 brake "upgrade" to my 1.6 just because I have the parts.

I was lurking and surfing through all of the need vs want comments on the complete, all four wheels brake upgrade including many who said it was a complete waste and only added weight.

I also came across a few comments from racers who found the stock brakes (with aftermarket pads) more than adequate, and who put the 1.8 brakes on the rear of their 1.6 to improve the brake balance and help rotate the car in corners under braking.

This 1.8 brakes on the rear of a 1.6 seems counterintuitive but it makes a lot of sense to me. It seems to me that although it's not the point, it wold still add something to straight line braking power because the rear on a lawyer-reviewed street car has to have significantly less braking power designed in than the chassis and a normal driver could otherwise handle.

Has anyone else tried this and found the balance or drivability to be better? If you were on the street has anyone found it to be dangerous (increased tendency for rear lock in the rain = oversteer etc)?

Wow my first "kill thread" on mt.net. Win!

I will just try it and post the results. It shouldn't take long to slap this stuff on the rear.

I don't know many that have only used rear 1.8 brakes, I'd suggest upgrading front and rear and adding a proportioning valve from Trackspeed Engineering, they have the custom fittings to bolt it in place of your stock non-adjustable proportioning valve, and then you can increase or decrease pressure going to the rear if you want more or less rear brake respectively.
