3.2V6 objective upgrades

Have my 3.2P3 back out and it’s still a wonderful thing.

It is though, by modern standards showing it’s engineering age.

Im not normally one to upgrade as I like things original and standard but the GTV has got me thinking of opening my wallet….money no object.

What I don’t want to do it needlessly spend money on stuff that doesn’t work.

below is a list of what I feel is needed to bring it a bit more up to date:

1. Steering wheel far too big. It’s massive and needs to come down a size. I wouldn’t want a Sparco or anything aftermarket but would consider a wheel from the Alfa stable….what are my options?

2. power steering. Too light and doesn’t weight up

3.Suspension. Firm, crashy and wallows in the corners. They must have worked hard to get all three

4. wooden brakes. Looking at the weight of the car vs the size of the discs (have the larger Brembos) they should be fine but there is a total lack of feel and thus confidence

Back in the day I would have defended all these issue but things have moved on and want to see if I can address all the above issues and I’ll probably think of a few more.

It has a Q2 BTW

Interested in thoughts from GTV owners who have successfully addressed any of these without ruining the car.

I feel several of them can be attributed to the front suspension and it being a single wishbone setup.

Oh, gear shifter throw too long but I have got the short shift kit but not fitted it yet. Good or ruins the silky feel?

My suspension feels good with the Alfaholics anti-roll bar kit, koni yellow shocks, suplex oe spec springs and replaced bushes (oe spherical bushes where they were originally and powerflex where there were standard bushes), a strut brace, side braces (totally alfa), coupled with a qualfie diff, its lovely and flat in the corners. Its absolutely fine on half decent roads, but doesn't deal with pot holes very well.

If you're going to try and get a modern car luxury feel then i don't think you will get it with a GTV, but i like my setup. Phase2guy on here has kw v2 coilovers, he might be able to tell you how they feel, i haven't bought them yet to give a comparison.

Are your 'big brembos' the standard ones or the 330mm upgrade? For a lack of feel i would change the fluid, discs and pads to some decent make and change the flexi pipes to braided ones.

Thanks for the reply CJC.

let’s look at the brakes first. I was under the impression the early 3.2’s had smaller front discs thenquickly after they fitted bigger ones.

I had the smaller ones on my early 04 and they were forever wharping. My current one do not.

here they are: approx measuring 300mm

They're 305mm brakes. Get some 330mm brembo calipers & brackets from a GT 3.2, then use GT 3.2 discs & pads. It's all a straight fit. Although I'm not sure whether those split-5 spoke 17" wheels clear the 330mm setup, does anyone know?

Or these if you have 18" wheels

These were on my car when I got it so can't compare to original. Feel very good though could probably do with replacement (v expensive Ferodo DS I think) pads for optimum performance. Seem like a good upgrade comparing my experience to other owners comments re standard brakes.

Can anyone running the 330’s on a GTV give an opinion. Awesome or mildly better.

how do they feel, progressive or wooden?

I'm running 330s Conaero... with performance friction pads.
Although I'm not a 'flat out' driver I could feel the improvement over the standard set up.
Plus... the biggest improvement is the looks. They now totally fill the wheel.

Interesting to see you also think the steering is light and doesn't weight up. Mine also doesn't self center.
I have just completed a total suspension restoration and was expecting a transformation but its now worse! [emoji2371]
I'm currently investigating several things at the moment.... but one of the things mentioned was the caster of the front suspension has to be spot on.
I did have a 4 wheel alignment after the refurbishment but am still struggling.
It doesn't help that my other Alfa... a V6 GT feels fantastic in the steering department. But like you mentioned that has a double wishbone set up up front. [emoji848]

I havent driven a GTV, but from driving a 2.0 and 3.2 GT, my first suggestion would be looking at the sway bars when tackling the handling, i dont know what a GTV/spider has, but the thicker bar on the 3.2 GT improves cornering significantly. I think that should be a first upgrade on any car trying to improve handling.

I am running 330 brakes on my P3

Definitely an improvement on the standard ones.
In my experience the biggest improvement in ride and handling has to be tyres. For years I used Bridgestone Potenza as fitted from the factory. They had a low profile and a very stiff sidewall. Fitted Dunlop Sportmaxx on the advice of my tyre fitter. Much more grip , much less road noise and all round smoother ride.

Got 330s on my GTV… a massive improvement but it is a Twinnie so the original brakes weren’t the best.

I have the same upgrade on my TS, Brembo calipers from a 166 with 4mm spacer to allow fitting 330mm x 32mm EBC discs and Bluestuff pads. Not fully run in yet but a great improvement on standard Twinspark set-up.

I used to have a Ph1 TS GTV, which I brought back from the dead.

When I recommissioned it, I put new pads and discs in, along with new hoses, and bled it all up.

And yet still the brakes were wooden, and not very powerful.

When I replaced the engine (like I said, “back from the dead”) I took the opportunity to replace the brake and clutch master cylinders, so I knew any brake problems didn’t originate from there. That just left the calipers themselves…

So I stripped, cleaned, and rebuilt all four calipers. The pistons were fine, but the seal grooves in each caliper had quite a bit of muck build-up behind the seals, and every caliper had damaged seals on the slider pins.

Suddenly, the brakes were OK again. Not great, but serviceable.

The guy I sold the car to subsequently put a set of the smaller Brembo 4-pots on it (with the 305 mm discs) and the brakes were suddenly better again.

So I think there might be two factors at play - sticking caliper, and a master cylinder that’s marginally too big. I think they used the same MC for single-piston AND 4-pot calipers.

Cheers
