Ok so here's my car as is with the 20" Callisto's on her......



looks pretty good, but, I'm thinking of a change to these



Now they come as a staggered set, which I DON'T want, so it's either fronts or rears, depending on which may be the best fit / look, so looking for any advice
My existing Callisto's are 9J with std 255 35 20 tyres on them
My choices ( assuming they'll both fit are as follows )

I believe that I'd like my wheels to protrude a little more ( I think I can get away with perhaps another 20mm there or thereabouts, need to check )
Fronts in 8.5J fitting with the same ET49 offset same tyre would be as follows, The rim / tyre will move away rom the strut by 6.4mm and also inwards by 6.4mm
I'm thinking of 20mm hubcentric wheel spacers to get it back out by about 15mm for a more aggressive stance.......




OR........
Fitting the rears in 9.5J with the same tyre size ET26 offset which would be as follows...



Basically, they'll protrude by around 30mm and it may be tight??
Looking for inspiration / thoughts / suggestions?

Hope to hear
Best

Jim , I've only just finished to day putting on my wheel spacers , I have taken them off several times and cut them back as the tyres kept rubbing on the wheel arches .

This is what I have : Factory fitted " performance " wheels 19 x 8.5 j all round
tyres are 255 x 40

This is what I bought : 30mm thick hubcentric billet aluminium spacers

This what I did : Fitted spacers all round , fronts just touched the wheel arches over bumps , rears touched a lot harder .

Removed all spacers and machined them to 26 mm , fronts now don't touch at all .
Rears didn't touch over bumps but when the rear end dipped down they just touched .
Removed rear spacers and machined them to 22 mm they now don't touch at all .

Even with people in the rear seat it still only touched about the same , I guess that's the air suspension and height sensors doing their job .

Specs for the spacers are : PCD 5 x 108
wheel hub diameter 63.4 mm
wheel stud M12 x 1.5 mm

Jim if you go to my profile page , go into albums , the very first picture will show you how they look on the car , they do make a difference .

Thanks Sid.....
I'd really like to go for the the following

Existing wheels 9J with an ET 49 offset
Tyres are 255 x 35 x 20

To 8.5J with an ET 49 offset
Tyres 255 x 35 x 20
adding in 20mm hubcentric wheel spacers

This 8.5J will move the wheel inwards by around 6mm ( I think already I'd like them and there's scope to move them outwards by about 10-15mm )
Fitting these will have that affect and should be ok I think
The problem ( I think I have ) is that the wheel studs would have to be 20mm in length or less and I'm sure they're a little longer, probably 30mm or so

 

Jim
In order to get the maximum width I started with the 30 mm spacer , it's easy enough to machine down , as you see I ended up with 26 mm front and 22 mm rear

Given that both our wheels are factory fitted I would think the wheel offsets would be similar

For some reason there's more room under the front guards than the rear

As far as wheel stud height ( from new spacer to wheel ) total length was about 60 mm and fitted ok .

The original wheel studs that secure the spacer to the hub , was again not a height issue

I think that 20 mm spacers would easily fit your set up .
Cheers ,

Sid

 

Thanks Sid,
re the spacers, see here




20mm Hubcentric wheel spacer kit
These are precision fit 20mm Hubcentric wheel spacers, In this kit you get 2 spacers with studs and shallow head nuts
The spacers are a nice one piece billet aluminum with a 5x 108 PCD with a centre bore of 63.4mm and the studs are M12x1.5, Please note that the stud on the car can not be any longer than 20mm coming out from the disc, Spacers are made from CNC machined 6082 Aluminium

This is where I think I may have an issue
Jim

 

Jim , I understand your concern , if you look on the inside of your wheels you will see that between each stud hole there are pre moulded recess's in which your original wheel stud will fit in .

 

Thanks Sid,
yes I've seen that, unsure whether they have it on the ones I'm looking at, will need to find out.
I'm sure where there's a will there's a way..........watch this space...lol

Jim, the rears from that set will not work at all on an X350...

9.5Jx20 with ET26, bad news... I ran 9.5Jx18 ET36 off an X150 XK on my XJR and they rubbed the rear wheel arches, so with another 10mm from that poking out you'd have even more trouble...

The required offset does change with the rim width.

So for example with Sid's car, you have to keep in mind he's running 8.5" rims, whereas your Callisto's are 9"

Adding 10mm is no problem and looks great. 15mm is maybe pushing it depending on ET and width, if you want to avoid rubbing.

For example the stock 9Jx20 ET49, if you changed that to ET39 it looks nice and you won't have rubbing issues, front or rear. Going past that is where you have to start playing around with clearance.

If you change to an 8.5Jx20 and you want the face of the wheel in the same place, then it needs to be about ET42 - ET43, then for your extra 10mm poke out ET33. But the face of the wheel would be in the same position as the 9J with ET39.

If you have an 8.5Jx20 ET49 and run a 20mm spacer, that makes it ET29, which is going to give you rubbing issues. 8.5Jx20 ET49 with a 15mm spacer would be better for clearance.

 

Need to get moving on this as I have loads to do.....
In a week on Monday for new front bushes re the wheel shuddering issue as per another post

I need the weather / temps to improve so I can tackle the sound deadening in the boot and the door seals I want to try.
The hubs and calipers need redone!

Also possible front end and rear bumper respray all before June 5th, work / family / kids / and many other committments

 

Unless you have already bought new wheels, the best solution to me looks to be your Callisto's ET49 with 10 mm spacers, as suggested by Cambo

 

I guess I may be going for this look, see attached pics.....minus the lowering though, that's not my scene at all.

Funnily enough, I have also considered blacking out the chrome window surround too.....that's a maybe??

Although after speaking to my window tinter again on the issue of window tints, I may look at this again as it was is something I'd really like on the car. Attached Thumbnails

 

Well, wheels arrived today, have to say they look very tasty, can't wait to get them fitted.
I have a set of H&R 20mm wheel spacers coming with a view to checking how they look with them added, may be another week or so before I get around to them in all fairness though.


Car's going in next Monday to get front suspension bushes re done, so no point until that happens.

 

FWIW, I'm running 265/35/20 P-Zeros on 20x9 Sepangs on my '05 SV8 with no issues. Except that I become aroused looking at my car sometimes...

 

Hope you get sorted out Jim - That's a pic of what I have now, but that should mean even with the spacers yours will fit, only looking at the outside as you're not going wider. If I understand correctly when I had the 9J ET49 Cremonas fitted with 20mm spacers that was an effective offset of 29, which fitted without problem, but I'd say that would be as far as you could go and I'd say 9.5J would cause some interference issues...

The only other thing is when fitting the spacers try and find a good 6 sided 19mm socket with thin wall as the shallow nuts to mount the spacers are pretty easy to round off..

Hope it all comes together in the end and you're happy with it!

 

20 mm additional offset seems to me a bit much for the suspensions.
Usually 10-15 mm is considered as the max to remain on the safe side.
So far from specs will certainly lead to increased stress and wear.
Any feedback from people having experienced that, in terms of wear?

 

Simon - Thanks for your help, really appreciate it


The wheels are 8.5 J so losing around 12mm there overall, The outer rim will poke out 6.4mm LESS than before, adding the 20mm spacers should take it out from original by about 13.6mm or so, which I think will be fine
Wheels are here and waiting for wheel spacers to arrive to try fitment and check

Having said that, she's going in on Monday to have new front suspension bushes fitted so no point before then. I'll look at this after that, get the wheels off and repaint hubs and calipers then get them fitted!!

Also trying to sort my audio issues asap and once that's done I can look at installing the sound deadening in the boot and also the add on door seals to try.
Rear window tints a week on Saturday and then possibly, remove the chrome mirror caps and look at dechroming the window surrounds too.

 

So just an afternoons work then?!
Should all look good when it's said and done though.
I'll need to be busy with the polish before June at this rate! That's if I can get it back out and going again!

 

Now that's what I call a storage space, all nice n safely tucked up for the winter!


Also trying to fit in a front end paint job, sills and rear bumper whilst machine polishing the rest of the car before then.......may be a bridge too far

 

Well, here's the Senta's on the car as of today.....
Took the opporchancity to get the hubs n calipers all freshened up too, looking good, well pleased
Pics are usual camera phone quality, so not the best...............



I tried the 20mm hubcentric spacers and they filled the arches so much better and seemed to move freely with no issues, but as I only had 1 set for trial purposes, they are back off the car. I'm going to get 2 sets ordered and get them added shortly, so should look even better


more.....





Next up its the hubcentric wheel spacers to be added
Then the extra door seals and sound deadening to be tackled
After that it's paint time front n rear + sills and machine polish the rest of the car

Hooraa

 

Looking good Jim...
