Can definitely feel a difference with this installed. Pedal feels firmer, does what it's meant too. Quality and finish is great.
The MC brace was awesome! Very easy install. Looks good and fits perfect.
I have now used many gktech products on my R33. All have been very well made and have fitted perfectly.. I would recommend gktech products as zero disappointment!
Excellent quality, fitment and super easy to install. It works well to completely eliminate firewall movement for a firmer pedal feel. I highly recommend it.
Would of been an easy install if the bolt supplied that goes through your strut tower was a tad shorter. I actually had to pull my strut and put the bolt in backwards for to be mounted cause if you put the bolt in from the bay to the strut it actually hits the strut. Other than that it would of been a 5 star. Brake pedal feels excellent now!
