Ok, that makes sense, as you say the nuts are quite large which confused me a little, I hope I have said recesses in the back of 330s rims!

 

Well the nuts are too deep or the alloy recesses are not deep enough.

Chris's supplier doesn't do shallower nuts to the correct strength so

I've just ordered some M12 1.25 pitch (60 deg coned), shallow spacer nuts from driftworks.

£32 delivered for 25

 

The other ones I have seen DO seem to to screw to hub in the recess in the spacer and be below surface of the spacer. Otherwise would be a custom design for each wheel type.

I'll ask my mate who has just fitted some to his classic how they go.
His were from E P Racing.

 

Something like this, you can clearly see how deep the pockets for the nuts are (the nuts also look very similar to the shallow ones Scooby L bought from Driftworks). When fitted, the nuts are below the wheel mating face so no need for recesses on the back of the wheel. Pic is of 20mm spacers btw.

 

Don't wanna sound stupid but what is being done by have spacers

 

Make the wheels protrude more I'd guess

 

Gives the car the stance of ET+35 alloys without the cost of replacing/upgrading the alloys.

 

Interesting pic, my spacers have the coned countersinks, but not the additional vertical recess before the countersink..... will see how the new "shallow" nuts sit (I have recesses behind the BBS alloys so they do not "need" to be flush).

 

Spacers will affect handling and steering feel as it is equivalent to using a stupidly low offset!
e.g. http://www.1010tires.com/wheeloffsetCalculator.asp
Old wheels: 8 inch ET53
New wheels: 8 inch ET32
So a 20mm spacer is equivalent to fitting wheels with 32 offset.
The steering will have a dead feel IMHO, don't do it!

Besides wheel bearings will be more stressed.

 

I never listen to the voice of reason

 

I'm not a fan of spacers or low offset wheels as well for the reasons stated above, unless the suspension geometry is revised to suit set up.

 

Would you need the geo redone if you just change the offset, do the wheels not just sit further apart?

 

I'm going to get Litchfields to do a geo after they're fitted

 

Only ask as I had mine recently done and cannot be arsed to get it done again if I go and change my current offset with new rims or spacers, cannot see why you would nee dit done if just the offset is changing?

 

I'd hope the machine quality of the spacer would not effect the tracking, but you are changing the geometric shape of the suspension etc, by extending the track out.... it may have an effect..I'm no expert though.

I'm having it done because he'll be fitting the prodrive springs too.

PS, Just bagged a 2nd hand clear fog light lens and red bulb off ebay for £35

 

Thats the thing I had my geo done a few months ago when my pd springs went on.

The clear fog will tidy the rear up nicely.

 

If any of you guys have anything other than a 55 offset rim can you please post up some side on pics so I can see where they sit in relation to the arch.

My current rims are 55 and I have been advised that a 30 will give arch issues so have been looking at 35's, however I've been told with lowering springs these could also cause arch issues so am now thinking maybe somewhere inbetween, just been told a 48 sits nice but the rims I like only come in a 35 or 55.

I've been told 35 is fine, it's 30 when things get tight

 

i have 35 of set, with prodrive spings

all fine, the tyre is about 15mm gap from the arch at the front, when you go full lock there about 3-4mm gap in the inner arch

 

Chris at CDF is going to increase the depth of the recesses, the shallow nuts are still too tall with the current countersink depths.

Working developments! LOL

 

Hi guys, thought id post in here too .......... i have a couple of bits for sale due to upgrades.

Whiteline lowering springs
These have been on the car for about 3000 miles but i have upgraded so have no use for these looking for £140.00 inc delivery.

18" Speedline Turni's in Gunmetal
Wheels are in mint condition tyres have covered about 1500 miles (mostly motorway) and have at least 6mm of tread on them. Tyres are 245/40/ZR18 Goodyear Eagle F1's looking for £800.00 inc delivery.

I have pics on both on my phone so if you want pics pm me you mobile number.

Thanks
Kev.

 

are the springs for the STi?, how far do they lower?

 

I need a bit of help here guys!

Trying to fit a Forge recirc dump valve tonight, started off very easily BUT could I remove the 2 cross head screws that hold the std ally return pipe to the body of the std dump valve.. NO!

Any one else done this - what size / type of screwdriver is needed ( posidrive or philips, and what size ? ) and any tips to get the screws moving?
Wary of rounding the screw heads!!

Cheers

 

Hi Paul,
Yes the springs are for an STi they lower it about the same as the prodrive springs i couldnt give you exact measurements i think it was 25mm rear 30mm front i think??
Thanks

 

does any1 know what the prodrive geo settings are for our STi's???

think i need mine doing due to pot caverns !!!!

 

Think the pd settings for the hatch are the same as the hawk, elite have them on file if thats where your going.

Cheers
A

 

if anybody is looking for a hayward and scott exhaust 2x 4.5 inch pipes 1 year old pm me guys £350 ono
for 08 sti cool sound ,just sold mine
cheers geo

 

Here's the geo settings that came with my Prodrive spring kit:

Minimum / Preferred / Maximum

Front camber: -0*50' / -0*55' / -1*00'
(for very aggresive use take this to max on adjustment approx -1*30')

Front toe-in (total): 0*08' / 0*10' / 0*12'

Front caster: 6*25' (Referential value)

Rear camber: -1*35' (Referential value)

Rear toe-in (total): 0*16' / 0*20' / 0*22'

Thrust angle: -0*01' / 0*00' / 0*01'

Hope that helps,

Neil
