What do I need for cup front suspension conversion?

[BenRS182]

Hi,
I have recently bought a 182 thinking it had at least the wheels and suspension cup pack due to the colour of the wheels. Unfortunately after measuring the hubs the spacing is 54mm, so the wheels must have been painted to a darker colour in the past or swapped etc. Not bothered tbh as this is my mistake.
I was looking into converting the front to fit cup suspension; all I know of as of yet is that I need cup hubs and cup driveshafts? Then I will obviously buy 60mm spaced shocks.
Is there anything else that is needed for this conversion?
The car will be a fast road/track car so will the conversion be worth it and noticeable?

Cheers 👍

If I remember correctly 172 cup suspension is 54mm spaced. So could just get those and don't go through the trouble of the conversion.

Most coilovers are available in 54mm bolt spacing as well.

Or is there another specific reason to need the 60mm spacing?

Thanks for your response! I thought I would benefit from having the cup hubs as they seem to offer more caster and be more suited for track going cars? This is my only real reason for the conversion, if the benefits arent that great then I'll just settle with 54mm spaced coilovers.
Thanks

I thought the 172 Cup, 182 and 182 Cup all shared the same caster?

Oh did they? Is there any real benefit to a cup hub over a non cup hub then? Surely Renault changed the hubs for the cup for some performance gain?
Thanks

182 Cup hubs and driveshafts (abs rings are different) are a pain.

I fitted them to mine and now I want coilovers, my choice is vastly limited.

Me personally, I’d stick with 54mm.

I have heard this elsewhere, there seems to be more choices of coilovers and shock with the 54mm.
I think you have helped me make my decision to stick with the 54mm hubs, thanks!

What coilovers are only for 54mm though? Same choice for either spacing surely.

Ph1 172 = 54mm
Ph2 172 & 172 Cup = 54mm
182 With Cup Pack = 60mm
182 Cup & 182 Trophy = 60mm

I was referring to secondhand.

60mm Coilovers rarely comes up for sale. Decent ones anyhow.

182 cup has a 25mm front roll bar. 172 has 22mm.

182 cup hubs also had increased steering acumen and a larger wheel flang over the 172 hubs.

I've seen this mentioned before, but never an explanation of "steering acumen". What benefits does it bring?

Just had a quick Google, when people are saying "acumen" do they mean Ackerman? I know what that is from my toy car racing days!

unless you're a total wheelman, right on the limit of the cars capability and competing in a competitive environment... Just stick with 54mm, loads less hassle for a cheap road car you may chuck on track occasionally

Perfect, thanks
Just the answer I needed 👍

For future questions about this- The cup hubs also have oversized bearings vs non cup. For spirited driving i think this is the best reason to opt for them- durability. My 182 has 115 k miles and still with the original front bearings
