Ah, your info is all correct, but the "GTA" wheels I bought turned out to be reproduction wheels like Reproduction GTA wheel from EB Spares. These have an ET of 36.5, hence my calculations above.

I do follow what you are saying about the 30mm drop only being equivalent to using up the first 30mm of suspension travel, so with the outer edge of the tyre outside the wheel arch it will rub with or without the lowering springs, but with the lowering springs will be hitting more often than without.

As far as handling is concerned let's be generous and say that handling characteristics are a personal preference. If you don't notice a deficit then fine, but with significantly wider track rear than front I didn't enjoy it at all. Maybe it is not so bad with the way you have that car set up but doesn't it look odd with wider track front than rear, or is the 8mm too subtle to tell?

I agree re handling, that's why racing drivers/riders set their machines up differently to each other.

I didn't realise that you only had spacers on the rear before, probably not such a good idea. In a fwd it's probably better to have a wider front than rear...I think.

My car's 8mm difference only came about due to the 16mm spacers being too wide for the rear, I drove without any rear spacers for a while & it still handled fine. I've left the fronts with 16s as the car looks good & I haven't got any more 12s...doubt I'd fit them if I had.

As your GTAs are ET36.5 then 15mm spacers will give you an 18mm wider track which I think is good & fill your arches better, only 1mm different to my rear end.

Thinking about it, what car has the ultimate narrow track front / wider track rear? The Robin Reliant. Not exactly renowned for good handling.

Thing is, wider front track than rear always looks retarded. Hell, the GTV looks odd enough with it's sunken rear wheels and more flush fronts from the factory. The GTV really is made to be styled like a RWD car even if this is at the detriment of handling!

There have been owners putting wider wheels (upto 9J even) on the rear to make the car look more RWD and therefore "cooler". I think that was what the previous owner of my car wanted to do with spacers at the rear only. I agreed it did look good, but didn't drive well.

Big difference with increasing track with spacers and tyre width, spacers are ok but effect handling.

May I ask how your car behaved with the spacers on the rear?

GTV is wider at the rear from factory!
It's a very rare car that has fwd and wider rear track.

...I was forgetting that but for the 'discussion' here I was more referring to wider spacers front to rear.

V6 rear track is 22mm wider than the front, if my book's correct.

When I only had 16mm front spacers & none on the rear it did have a 10mm(I think)wider front track than rear, handled fine & still does with the 12mm spacers now fitted to the rears which has again given it a wider rear track(14mm I think/hope?).

Wave Et, pcd, offset & spigot rings explained

This might be helpful:

WHEELS. PCD, offset, and centre spigot diameter

Not sure I agree with 20mm increase invalidating your insurance though!?

Insurance companies should be informed of any modifications, one thing as a car dealer I don't have to do or worry about.

Oh, I was talking about the way the wheels are. Even though the rear track is wider, the wheels appear to be further inside the body, pretty much, the GTV has a RWD styled body.

Run the same spacers/offset then get wider wheels on the rear with the same width tyre = won't handle like ****, and will look awesome. I'd stretch tyres if I didn't get GTA wheels.

Mine had wider spacers at the back and handled prefect! Well ofcourse it depends of the driving style and other things done to the car (mine was far from stock)

Again, same here. My geometry is so far off no wheel alignment place can give me proper setup to OE, so it's whatever I want.

Our front geometry was very similar Alan, but we'd done different modifications to achieve this.

It's about 9 years ago (yes, I've had the car that long) so difficult to remember except that it didn't give any confidence cornering, whereas with the spacers removed it did. This was coming from a Mk3 Golf GTi 16v - hardly a great handling car. I put it down to having ruined the passive rear wheel steering effect, then restoring it with spacers removed.
Since then I have powerflexed rear - better no passive rear wheel stearing than couter-productive. Also 30mm dropped springs at rear, Koni's at rear, Novitec coilovers (-28mm at present) at front, front strutbrace, front Powerflex since. In short my suspension setup is far from standard now.

Powerflexing the rear doesn't stop the passive rear wheel steering.

Your set up is basically just lower & stiffer/harder...which if you like it then it's good** but for most people, especially on our awful roads, it would be too harsh. I've got, & had, similar set ups & after a while they aren't comfortable for everyday driving...fun for a blast though.

**good for your track days.

Beware Powerflexing the front as apparently they can 'pop' out, not something you'd want at the wrong moment.

^^ So OEM would be the way to go then?!? Keep hearing bad stuff about aftermarket parts... I am buying genuine wishbones because I heard the aftermarkets balljoints can fail earlier and there have been reports of them shearing off.. that and I also found out that the balljoints wear earlier than powerflex so there is no point in doing it to wishbones anyway.

My experience is that powerflexing pushes the limit when passive steering effect comes in - and not by little. I tested that on our Grobnik racetrack and now I have to push really hard to make it happen. To be honest, I have found that casual fun driving is better with the standard setup!

Not bad ... somehow they suit a Spider more than they would a GTV.

GTV 2.0 JTS

I like the idea of some decent split rims for the GTV, the one in this photo in particular...

Alfa Romeo Shop - Tuning, Styling, Fanartikel und Modellautos - Alfa Spider und Alfa GTV Novitec Edelstahl Endschalldmpfer 4x76 DTM Novitec Edelstahl Doppel-Endschalldmpfer 2x 2x76 DTM 39047


Besides those...I've had 18's with OEM shocks and SPAX 30mm lowering springs and the ride was too harsh...I'm guessing with Bilstein shocks it would have made a massive improvement...

On my new GTV I'm running GTA Teledials and with 225 45 rubber and standard suspension the ride is alot more comfortable.
