The first thing you need to do for a faster Rover 75 or MG ZT

[rich17865]

Well, the tuning, go faster, vroom tish brigade seem to be taking over en mass.

So what is the first thing you need to do to your car to make your car faster?

Bigger brakes.

On a more serious note, not once have I seen someone say they want a faster car, so where should they get better brakes or suspension from.

I think the lack of interest in safety critical items is what upsets people amd makes them say "buy a better car" whenever tuning is mentioned.

So your saying you've never seen anyone fit larger brakes to a ZT / 75? Such as those found on the 190 to the rest of the range?

Righto then.

I've upgraded to 190 brakes, braided hoses and Brembo discs.
I've seen quite a few threads on people doing just this.

They are standard fit brakes what's your point?

Larger turbos, egr bypasses and decat pipes weren't an option, nor were other engine performance upgrades.

You have never seen anyone wanting more than 190bhp?

4 or 6 piston calipers, improved brake cooling, firmer suspension arm bushes, larger or multiple cooling fans, larger oil cooler, larger diameter springs, better anti roll bars, strut top braces, fire extinguishers, burst proof door locks, fuel and battery cut off?

Always about going faster, winding the engines up, and that's it.

Or am I missing the point?

I get where you're coming from but its all relative to the power you're going for - you don't need a parachute on a car that's putting out a little over 200bhp.

A lot of MG-R parts are quite well engineered and have tolerances well in excess of their intended use.
For example, the 1.8T is a 160bhp car but the crank is good for a safe 300bhp.
I'd be interested in knowing what the 190 brakes are good for, considering they're the same as those on the front of the 260bhp V8.

Suspension and brakes are more to do with the overall handling. Brakes have to be able to cope with the cars weight as does the suspension.

Doing 100mph in a 200bhp ZT or a 160bhp ZT will give the same stopping distance with the same brake set-up, regardless of how fast you got to a 100mph. Handling also won't be affected much by higher power (apart from maybe a bit more torque-steer)
There comes a point where the bushes can't handle the power or the wishbone becomes critical or the chassis start flexing etc. I'll doubt if anyone can take a 1.8T that far. And I'm sure that if they do, some of you're points will be considered

Some people just like the extra BHP other would like a modified car.
Each to their own.

Hi.
Id like to fit the 4 pot calipers off a Skoda Rapid (not the new model but the brilliant proper Skoda) these were excellent and were a direct decendant from the 130rs. Made a lot of sense actually as the car handled beautifully and point to point progress could be very fast, often quicker than much more powerful cars so good brakes and suspension make a lot of sense even with just cooking power.

I doubt if there's a BHP rating for brakes. It's about slowing a 1.7ton car down so more to do with vehicle weight.

V8 has the same front brakes as the 190 and the rear brakes are even bigger than the front ones at 332mm.
Maybe because they shifted the brake balance more to the back, maybe because of the inertia of the differential.

I quite agree, more power doesn't mean you need a shorter braking distance.

I have a tuning box in my van, because it is a bottom of the range 85bhp slug. I really appreciate the extra effort it gives as it can get me out of sticky situations

However, in general people who want more power want to use it all the time, accelerating hard, maybe just to the speed limit, maybe not. As a result, will brake harder and more often and suffer brake fade, overheating or boiling of the brake fluid.

The same sort of driver will think they are in a rally car and corner at speeds in excess of what the rest of us would seem appropriate.

This is the sort of mentality I detect often here, not the sort you refer to Herman.

I have to say, the 620ti has the largest brakes fitted to a Rover 600 (282mm) and they do get rather scary if you're slowing down from warp-factor speeds.
I've just been on the Autobahn, and really felt fade as I slowed down to exit!
