Brake booster performance w/2cam swap

[Drew325is]

When using any of the brake boosters required for a twin cam swap (e.g. 325ix etc), is there any change in pedal feel?

I have an '88 325iS and I'm using Wilwood 4 piston front brakes...the stick 325i booster works perfectly with the Wilwoods, but I'm worried using the different booster might upset things...should I be worried?

I've got the e21 booster, but with the stock e30 master cylinder. Most people upgrade to the 25mm part.
Pedal effort was definitely slightly increased, but I quickly got used to it and the braking power and feel is good, especially with new pads and rotors and stainless lines.

Can you get your brakes to lock up brew? I cant. I think my booster is on its way out... I'll probably go for the ix booster when i replace it.

Yeah, I've had the ABS to kick in at 90+ while chasing down an e46 m3 that some jackass cut off. :) Brakes are very strong, just require slightly more pedal effort.
