Anyone out there able to confirm this.

Sent by a guy who makes hubs and spacers but not sure myself what i need

please check this for me:
Got: 2x15" and 2x16" of 4x108 ET25 and center bore 63.3mm
Want: 4x18" of 5x114.5 or 5x120 ET33 or ET42

Mark.

My 5 stud hubs were on the car when I bought it.

I might be able to confirm from where though.

I'll check.

Mark, you need to find out whether they are 5 x 114.5 or 5 x 120 - they cannot be both.
Start a thread on the Tuscan forum, or call someone like Str8six. Don't order hubs until you have found out for certain.

BTW, your original rears will have been ET33, not ET25. otherwise correct. Your new ones, as already you know, are 2 x ET42 and 2 x ET33

I had a word with Precat, (griff owner and friend)and he thinks from memory that he supplied my hubs when he did a few kits some years back.

He adapted, remachined and fitted new high quality studs.

It's a bit of a process and he said that for what it's worth, it may be easier to buy a set from Hans the Dutchman.

If you want any further info, send a pm to Precat.

I have a set of front et42 and rear 33 if i use the fronts on the rear with a 7mm spacer and rears on the front with an 8mm spacer it balances out perfectly, with 19mm wider inboard and outboard on the front and 13mm equally on the rear

HELP
I have just bought a set or 18" front and rear wheels,do i need to swop round and add spacers,or buy another set of rears and sell the fronts???

Sorry Richard just read you original statement correctly.....its all in the wording!!!!!

[CHIMV8]

They do look the dogs when the spiders are on

[CHIMV8]

Nearly sorted the 5 stud hubs

Any one give advise on how to swop over hubs DIY rather than paying someone please>>

[CHIMV8]

Is this the way

Just to give something back to all of the great info I have 'scraped' over the last few months, I am 90% through fitting 18" Spiders to my Chim 4.0 (1994) and I did the following;

Procurement :-)

- Purchased 4 x rear Spiders from eBay (et33)
- Purchased 2 x 8mm spacers for the fronts to meet the Chim +25 offset
- Purchased 4 x spigot rings (70.1 - 63.4) from eBay (Tuscan bore to Chim/ Sierra hub respectively)
- Purchased 4 x new decals from eBay (domed TVR logo)
- Yet to purchase 4 x anthracite locking wheel bolts and grey caps for the existing 16 bolts

Real work :-)

- Had the Spiders refurbed - dipped, blasted and powder coated by Lesshop in Abedare (Wales) for a very very cheap price, they look new
- Had the hubs modified at a local engineering firm with hubs and disks re-drilled to PCD 5 x 114.3, with a steel ring welded to the back to compensate for the weakness/ overlap
- Had the disks skimmed also
- Re-used two of the front studs to make up two sets of five for the rears
- Engineering firm purchased 10 x new studs for the fronts at 8mm longer to account for the 8mm spacers

• * Updated to say that the longer studs are required to accommodate the steel rings which are fixed to the back of the hubs to accommodate hole overlap and the fact that the new holes are just 2mm from the edge on the fronts. I had previously thought they were required to accommodate the spacers, however apparently this is not the case. ***

Hope this of help to someone, pics should be up next week when all re-assembled.

Before (this refurb was done with no filler, just sanding, due to the temperature of oven and filler melts):

thanks mate, i'm very excited to get them on, it's a big job and I couldn't have done it without all of the knowledge I've silently scraped from this forum!

As I understand it, in an ideal world you would have 8mm longer studs on the fronts to account for the 8mm spacers and I have asked the local engineering firm (in Clevedon) to do this.

.... and just for a laugh, the guy I got the Spiders from got them from a guy that had them on a Peugeot 306!!

I can answer that.
I tried 7mm spacers when I changed wheels to ET40, but there was barely three turns on each wheel nut = far too little.
Changed the spacers for 5mm, now have enough turns of each nut easily for safety. Quite surprising what a difference 2mm makes. It felt like about 4 turns from memory.
