Title: MR2 Mk3 Wilwood Dynalite Brake kit
Post by: 4dvti on March 26, 2016, 16:27
Hi Guys

I hope this message finds you all well, even though the weather isn't so kind today (here in the W Midlands, atleast!)


I've been recommended the attached brake setup for the roadster and was wondering whether anyone has any experience, insight or general information on them. I was told that they will fit under most 15" wheels, which is the main reason why I am looking into them. The mr2 will see high speeds a lot at both the 1/4 mile and standing mile, having already gone at over 150mph last year, so better brakes are definitely required.

Here's a link the the setup:

Enjoy your Easter vacation  s:) :) s:)

He was running a group buy a few lads had the front kit.

Thank you for your reply. I've just read some of the thread and skimmed through the rest.

It would be nice to hear how users have got on with them one year on.

What worries me is the change in brake bias with these. But I haven't done any research into it yet. I know most people have to find an alternative solution for the rear as there isn't an option for them.

Are you sure that uprated brake fluid, braided hoses, uprated discs and pads won't do it?

I guess you'll be using slicks for the drag racing so I guess they have huge amounts of grip for such a light car?

I agree with the brake bias comment. Fitting only the front kit must change the brake bias so there is more braking power at the front compared to the standard set up. I suspect this may well reduce the total maximum braking force available because the ABS will kick in when the front wheels lock up well before the rear wheels get near peak braking effect.

The bigger brakes will give more resistance to fade so if you are braking repeatedly on a circuit you will see that benefit but as I say I suspect the ultimate stopping distance would be worse because you are losing braking power from the rear compared to the standard setup (which is already capable of locking the front wheels anyway) so you aren't getting anymore maximum front braking capability from the new setup to offset this loss at the rear.

I understand there is also a rear brake kit available, with handbrake, which should overcome this issue, but that's another few hundred quid....

Personally, for a standard road car I would prefer to have the best maximum braking power available for a one off emergency. Fade resistance isn't something I worry about.

With my build I have put Alcon 4 pots on the front , the front has 305mm rotors and bells, the rear has grooved ebc discs and standard MR callipers EBC blue on the front and yellow on the rear. I have no ABS or servo but do have a bias pedal box with dash adjuster ,with my last 2 rally cars I found keeping the brakes cool with ducts has always really helped.

Thanks for all the feedback and information guys. This is actually more complicated than I thought.

I should also add that the car will be 350bhp or more in the coming months. Now I'm thinking I should stick to the stock setup and then move onto braided lines, new fluid and better pads. If that doesn't do it, then it'll have to be aftermarket. Having read your collective comments, I don't want to jump straight to the aftermarket front setup now.

Thank you everyone.
