Hey all

My first post on here having bought an F Type a few weeks back. Hope you don’t mind me coming straight in with a question?

I’m planning on getting some of the Velocity progressive springs with the small drop in ride height. However I’d also like to space the wheels out slightly. The ideal would be about 15mm but I understand I’d have to shave the studs. I’ve read on here a company doing some 17mm which were designed to negate the need for stud shaving, however I also read some still have to?

Ive got the carbon blades fitted to my car, does anyone know what the minimum size spacer I need to get where I don’t need to mod the existing studs?

 

You can go with the 17mm spacers, but don't plan on lowering the car (15mm needed for that). If the 17mm spacers still cause an interference problem, you can always buff the additional clearance from the inside of the wheel (much easier than grinding hardened steel). If you do this, I would suggest rebalancing the wheel, but given the minimal amount of material to be removed (~ 10mm dia x 1mm deep at 5 offsetting locations) that probably isn't necessary.

 

I have the Blade wheels and VAP lowering springs and 15 mm spacers all round, and I have had zero fitment or rubbing problems.
Lots of posts here about 17 mm vs 15 mm spacers and needing to grind 2 or 3 mm off the studs, but as I have reported many times the Blade wheel does NOT need any grinding, not even with 15 mm spacers, as it has deep enough recesses between each stud hole for the original stud to fit comfortably with zero interference.

 

I have an SVR with 305 rears stock.
I just orders VAP springs and 10mm hub and wheel centric spacers (not adapters) that I will use with extended thread lug nuts. The plan is everything comes together fine.
Wish me luck ....

 

Any updates on your mods?

 

Mark999, take a look at the group buy thread going in if you are still looking for spacers. We are likely going with the majority size most people want (15 or 17mm).

I believe things went swimmingly!
305 rear tire (stock) + 10mm wheel/hub centric spacer + extended black lug nuts + VelocityAP springs = finished and happy.

 

Are there pics? I would like to see this before I "take the plunge".

 

I can shoot pics this weekend.

 

Where did you get the spacers and lugs?

 

Spacers: Motorsport Technology (Lenny). Make sure he knows you are using extended or shank style lug nuts so he will make the holes a little bigger (so your nuts won't touch the sides of the spacer holes).
Lug nuts: Gorilla Lug Nuts 73137BCB (purchased from Summit Racing)
Lug nut washers:McGard Stainless Steel Mag Lug Nut Washers 78713(purchased from Summit Racing). I wanted heavier duty washers than what came with the Gorilla lug nuts.
Lowering springs: VelocityAP

Keep in mind my stock 20" Jag wheels (ceramic brake package) use a flat washer style lug nut.

I had 3 jaguar service master mechanics review the parts/install during the install. All good.

After 200 miles on twistys, torque on all nuts has remained at 92.

 

Do you remember how many turns you got with your lug nuts when tightening? Without spacers, I'm at just about 8 turns to full tight, and I'm afraid a 5mm spacer won't give me enough engagement.

 

i know its been said but in all honestly your only shaving the tip (if anything) off the stud, no threads. Use a $12 grinder from HF with a cutting wheel (if you don't already have a grinder/cutoff wheel) and it takes less then 5 minutes to cut all 20 studs tips off. Hint: put the nuts that come with your spacers on the studs before you cut it off in case you damage any of the threads this will clean it up when you take it off.

 

Josh,
he’s talking about 5mm spacers, not 15mm adapters. I did the math. Up to 6mm spacer is safe and will not compromise thread strength. A 10mm spacer will work ok under gentle street use, but I wouldn’t be testing 1+ Gs.

 

Thank you! This is exactly what I was looking for.

And by chance, do you remember how many turns that was of the lugnut? I know you're running a 6mm spacer in the front -- wondering if you could share how many lug nut turns you had there? I keep reading 5 is the bare minimum, and I'm at just about 7.75 with no spacer. Wondering if I can run a 3 or 5mm spacer?

 

good call, i didn't read all the comments...i always assumed 5mm was the max for a spacer type, and 15mm was shortest for adapter type. thanks for the clarification Lance!

 

I really can’t remember. I was using a 6mm at the time since that was the only shim I had available to get big brake clearance on my VS Forged wheels. I have since replaced them with 3mm spacers.

The number of lug nut turns you get will also depend on the specific wheel being used.

BTW, 1 turn represents 1.5mm on a 12 x 1.5 bolt.
If you are at 7.75 turns without spacer, you can install a 4mm spacer and still have at least 5 turns left.

 

Yeah, unfortunately you're right in regards to the specific wheel. For whatever reason, BC Forged did not drill the holes very deeply, and as a result, I don't think I'll be able to run a spacer without either extended studs, or extended thread lug nuts. I'm doubtful the latter will work given that BC also drilled the holes very narrowly.
