19 inch alloys on an M,advice from those who have.

[craig3.2]

On my OEM CSL’s I had 10mm spacers on the front and with my latest AVA’s I have 20mm on the rears the ride isn’t as good on 19’s imo

I like the photo of your Datsun 240z getting in on the photo,Darren
Always fancied a drive in one of these,nice classic car. Love the colour too,that's a few years you have had it now, isn't it?
How does the OEM csl wheels affect handling etc,given they are the wrong/different offsets from the OEM 224 z4m alloys??

Thanks Craig I think I’ve had it about 3 years, taking it to the Le Mans Classic in a couple of weeks

I didn’t notice any difference tbh, only in ride quality, you don’t need to put the spacers on the front, many don’t, I just wanted them flush with the front wing, the rears fit perfectly, ET27 Rear, ET44 Front iirc

Nice,Darren

I thought the OEM 224 alloys offsets were 32&40,front&rear?
Doesn't that different offsets on the csl wheels matter??

The rears go straight on and fill the back Craig as do the fronts but are inside the arch a little, that’s why I put the spacers on the front, CSL’s are different widths to the 224’s I think so that’ll be why the offsets are different, I’m sure someone will explain better than me they it anyhow

Craig, put the details of the wheels into an online tyre calculator. It will give you a visual picture of the differences between say 224’s and CSL’s. How much further they stick in and out, and the diameter etc.

Looks great Darren This could have been taken as it left the factory (ignoring the cars in the background).

Previously, I had CSLs fitted with Eibachs and OEM dampers as well as a strut brace and I ran the maximum obtainable negative camber through pulling the camber pins. This made the ride truly horrible on rough roads compared with running 224s and the same suspension set up. The front wheels followed every furrow in the tarmac and the car was very skittish and unpredictable. The handling on the track using 224s was significantly improved with this suspension set up over OEM and I preferred the look of the CSLs, so I kept running this with the CSLs on the road for a while.

I then fitted KW Clubsports with camber plates and H&R ARBs as well as making numerous other suspension changes. This transformed the handling on the track and changed the ride on the road to tooth-breakingly hard but well controlled (although it remained skittish unless I backed off the bump and rebound). With this set up, I had to use 5mm spacers with my CSLs to adequately clear the suspension.

I’ve recently fitted an AP Racing BBK front and rear and no longer require spacers with my CSLs.

Overall, I suspect that CSLs with OEM suspension would be a reasonable combination, but I would avoid 19” wheels with lowering springs especially when running more negative camber.

Thanks Richard, it is totally original apart from the wheels which are a modern version of what would’ve been available at the time and triple 40’s which were also a period upgrade, I have the OEM wheels and restored caps too sorry for the High jack Craig

Will you be able to keep up with my 260 Darren,give you a race to Le Mans mate first one there gets the beers in,Z is looking good,pick the m up on Wednesday

I eventually grew tired of the ride on 19s, having gone from 224s to CSLs. Now I’ve gone up a profile size and I think it’s a good compromise between looks and ride/handling, but although 265/35 is a comfortable fit on the rear, 235/40 is too much on the front (without arch liner modification and minimal suspension drop).

265/35 and 245/35 would be perfect, I reckon - in fact, this is similar to what you’ll find on current gen M2s and Caymans.

I think you’re right... I like the stock 18s just as they are too.

What spacers would you recommend though, if at all? Thinking Eibachs but not sure what width just within ‘sensible’

[Papa_Zee]

OEM CSL’s with no spacers. Dropped 25mm on H&R’s

This exact photo was my inspiration for upgrading to the Z4MR from my DD 2.0i which I still own. Neighbours must think im bonkers...

So, yes I think this is the way to go from my stock 18s. Not too keen on spacers either.

Thanks!
