    Calling all 400 owners who have switched to 16" wheels (most likely SF 16x8 QV rear repros). I have read all the threads and come to a decision to go this way. Then I fitted 17's, which I got for a good price with tyres, so it got me mobile. The trouble is, the 25 year old Pirelli P-Zeroes are rock hard, and the ride is terrible. The 17's are 8.5", so a little wide to go narrower than the 245/50's on them, and I'd like to go a bit narrower and taller for ride comfort. 225/60 R16's seem to be the go. And yes, I flirted with going back to the good old TRX's, but at A$3000 a set, has given me pause!

    So could the 2-3 of you that have done this get back to me with your current views on ride, noise, handling, and what spacers may be needed?

    Cheers

    Wow a 400 with 17”s. Gotta see that, post pics!

    Personally, I love the TRXs.

    Patrick,

    Lucky for me you bought those 17” wheels – ugliest wheels I have ever seen. Saved me taking them to the tip :)

    Now, to be more constructive, I have a set of 16” Simmons wheels (7.5” & 9”) that Tony Simmons made for me when I had the C4. They have Michelin Pilot Sports on them that were the best road tyres available at the time.

    There was no comparison between the performance of these and 15” Borranis with XWX’s – made the C4 feel/drive almost like a modern car. Much better “turn-in” and generally better feel on the road.

    Of course, a lot of this is due to the stiffness of the Simmons compared to Borranis, but they are still a lot better than a 15” Campanoglo & 70 Series XWX combination.

    I love taking money from quacks (a kind of very small revenge, if you like) so do I have a deal for you!

    Option A - You can buy a set of splines to bolt on to a 400/400i from Turrino Wheels (Tasman 246) for about USD1500 and buy the 16” Simmons from me.

    Option B – The bolt pattern for Ferrari splined wheels is the same as for 308/400 wheels so you could drill the Simmons to the larger bolt diameter and then they would bolt straight on to the 400. (The splined hubs are worth good money in themselves).

    Personally, if I were you, I would just swallow the cost of a new set of TRX Michelins (unless you plan to run the 400I in Targa Tasmania instead of my old Lotus Elan).

    I think you might be surprised how good a set of new TRX’s are compared to those that are 20-30 years old’

    Regards

    Option A - very funny
    Option B - hysterical
    TRX's - I've gone through all that!

    I'm going to probably re-shoe the 17's with something narrower, taller, and softer, hopefully with a less square shoulder than the P-Zeroes. Marc offered up the SF 8x16's and it looks like large spacers might be needed. Still waiting to hear from someone who's done it.

    Just put 235/55 R17 Bridgestones on. The remit was to give good ride as priority one. Definitely has improved the ride, also very quiet. Can't tell much about the cornering yet.

    Yep, and after work this morning I'm going to spend a happy afternoon fixing the ignition switch and some general tinkering. I'll repost the pics over here.

    They all do. Look at your sill line - nice and parallel. Mine's slightly up at the back, which I did to clear the super wide tyres it used to have, but I still think the Koni spring/shock kit to replace the ride leveller is too soft, so I might yet stiffen it up.

    your self levellers are probably stuffed. I had the Koni coil over replacement fitted to the C4 and even IanB remarked when driving it a very high speed :eek: that the suspension set up was perfect. I have the old self levellers in the garage somewhere, not sure if they are good or not

    I'm freeze dried from the eighties - you like what you like. Besides, it's only 10 mins from Gezim's place. :D
