[Mike.Bray]

Very nice! Love the SBF. Welcome to the fun!

Are you planning on taking it to the track? Just curious about the sway bars.

[danmas]

I think so, but, not a lot

[danmas]

Ordered an 8 stack EFI system from Jim Inglese.

I am considering these wheels to go with my build. I haven't made up my mind yet, but, thought I would check with you all.

Volks_CE28_CRII_MM.jpg

Fronts: 18x9.5
Volk Racing CE28 Club Racer II Black Edition Wheel 18x9.5 5x114.3 22mm Diamond Dark Gunmetal

I don't know if a +22 offset is too close?

Rear: 18x10.5
Volk Racing CE28 Club Racer II Black Edition Wheel 18x10.5 5x114.3 15mm Diamond Dark Gunmetal

15mm offset. I have heard/read that 18x11 is the preferred choice for the rear, which seems reasonable, but, Gordon Levy point me towards these wheels. Thoughts?

[Papa]

Congrats, Dan! Hope to see you on the road when you get it done. Give me a shout if you need a hand.

Dave

[KayzDad]

My kit should arrive in mid-April, and is configured similar to yours. Looking forward to following your progress!

[danmas]

I will take you up on your offer! Never dropped an engine in a car before, so, lot of firsts for me..... Thanks for your advice on the engine and EFI!

[danmas]

Decided on these after working with Gordon for a few days. Need them because of the massive brakes.

Wheels:
18x11 Matte Black Wheel Konig Hypergram 5x4.5 15
18x9.5 Matte Black Wheel Konig Hypergram 5x4.5 25


Also think I purchased the hardtop to go with the roadster that @madfor67 was selling. Going to be a fun build!

And I had to order different rollbars.

Are you planning on building the engine yourself ?

Not this time around. I don't have the skill. I am having it built by a shop that Jim Inglese uses. In the future I have ambitions of getting to that level of detail. Right now its all about getting my first car together.

Dan, I live in "Parker" and my kit is to be picked up by Stewart April 15th. I am waiting to hear from Stewart for a delivery date. It sounds like we will be building at the same time. I will keep watching your thread. By the way I went and got the full tour at Papa Dave's garage. It was worth the time. I appreciate all the knowledge he has and shared with my son and I. We are building together.

He has been advising me for a couple years now. I redid my entire engine build based on his advice. I haven't made it down yet to see his kit. I actually am incredibly grateful to this community so far. I have spent the last 7 months or so thinking about the building and learning a bit every time I come here. Nights that I can't sleep I typically check in here.

I think yours is coming before mine. I am building with my three daughters. Love to hear how your build goes. I think my next task is to build body buck and so forth.

What does your config look like? Post your build thread? As an aside Junbug is here as well and ahead of us. He found a pretty awesome powder coating shop.

[danmas]

Just got my call from Factory Five and solidified the order. Stewart transportation has me on the books and sometime in early May I will be a brand new cobra dad.

Yay!

Dan

[JV1953]

Hi Dan,

Congratulations!

I have a frame dolly that I am finished using it is yours if you want it. I'm in Firestone.

[danmas]

Yes!~ PM Sent

[danmas]

Got these picture for the hardtop I got from @Madfor67. It is possibly going to be the very first thing I get for the car (which seems backwards I suppose). None the less I am pretty excited!

Dan,
If you haven’t completely made up your mind on your wheels. I recommend looking into Forgestar. I just gave them the FFR offset and backspacing specs for the wheels and they custom build them for what I thought was a reasonable price. And they offered free shipping when I ordered. Either way you go I’m sure they’ll look good!
Please reach out if you have any questions. My kit was delivered in Jan!

Thanks! I ordered a set of Konigs and they showed up today actually. Sick looking wheel. I think these will work.

[danmas]

Tires:
Nitto NT555 Gen 2
2 x 255/45/18 diameter 26.7 for 18 x 8.5 / 9/ 9.5 inch wheel.
2 x 315/40/18 diameter 27.91 for 18 x 11 /12 inch wheel.

[topherchrisb]

I can't wait to see your wheels. I was bummed to hear about the leave time on the Volks... I hadn't seen those till your post and my are the good looking! I have been going to Forgestar's site a lot and looking at their offerings but couldn't find anything in the proper size. I'm glad to hear Junbug got some help when interacting with them directly and I'll likely do the same. Now looking at his build I'm afraid I might end up picking the same set! I'm not a complete copy cat I swear.

CO front range is funny. I grew up in Del Camino right next to JV1953's Firestone. Because of that I went to Mead all through elementary and middle school. Before now living in Frederick (about three miles from the house I grew up in) I lived in Lafayette near Wanaka lake. I have a little bit of family in Mead and I know a number of people out there.

Wheels!

[danmas]

Talked to i.e.427Garage and scored an unused RT drop trunk and old style trunk lid that will fit my hard top. Got my FFMetal Firewall Forward and fat tire wheel wells. Parts are starting to come in.

[Jeff Kleiner]

Tires:
Nitto NT555 Gen 2
2 x 255/45/18 diameter 26.7 for 18 x 8.5 / 9/ 9.5 inch wheel.
2 x 315/40/18 diameter 27.91 for 18 x 11 /12 inch wheel.

You might want to give some thought to those tire sizes; the 255/45-18 is approximately 1.7" larger in diameter than the usual 255/35-18 or 255/40-17 which are both 25.0". In the rear the 315/40-18 is over 2" larger in diameter than the usual 315/30-18 (25.5") or 315/35-17 (25.7"). Unless you run an unusually high ride height I'm afraid you may find that you have conflict, especially if the rim's offsets move the tires farther outward than the FFR wheels.

Ugh. Guess I will see. This is what Gordon suggested (255-265 fronts and 305-315 rears) so this is what I got. I didnt even think to check if it would fit in the wheel wells. If its wrong I am sure it won't be the first mistake I make. Thanks for the heads up.

[i.e.427]

When ever someone asks about wheel and tire fitment for one of these cars I always steer them to the FactoryFiveParts website. Pick your wheel diameter and scroll down to fitment and recommended tire sizes. https://www.factoryfiveparts.com/158...eplica-wheels/

I have this thing where I consistently order the wrong thing. I am not certain why, but, given half a chance to pick the wrong size I do it 90% of the time. Anyway, returning and getting the right set. Probably Michelin Pilot Sport

Rears:
Michelin 09883 - Michelin Pilot Sport PS2 Tires
Tire, Pilot Sport PS2, 315/30-18, Radial, Y Speed Rated, 98 Load Range, Blackwall

Fronts:
Michelin 27579 - Michelin Pilot Sport 4 S Tires
Tires, Pilot Sport 4 S, 255/35-18, Radial, Blackwall, Y Speed Rating, 94 Load Index

Before I pull the trigger on these is there anything I am missing?

I also picked up a pair of pipes and headers from George over at Gas-N.

Dan,

The Michelin PS2 and PS4S are similar tread designs, but different compounds. I'm not sure it makes any difference for street use, but will defer to others that may have more technical info to share.

I'm not a fan of mismatched tires front to rear in any case (unless you're talking snow tires on an old 2WD pickup truck that hauls firewood ). Those Michelin that you spec have a harder compound for the front than the rear---with the factory spring rates these cars understeer to begin with and using a tire with less traction in the front will just exacerbate that condition. If it were me I'd just put Falken RT660s all around. But you're not me... With that said I'll say one more thing; unless you're planning a really quick build I wouldn't buy any tires yet. They're just going to sit, age and get hard. Wait until you have a running gocart to mount up fresh tires and in the meantime spend a hundred bucks on a set of junkyard wheels and "skins" to roll it around.

This is great advice and exactly what I will do in terms of getting crufty wheels and skins to roll around on. Thanks for the pointer on the rt660s, this is the kind of expert advice I need. Thank you...

Kleiner and I agree on this point. Most tires on these cars age out before they wear out. Save the expensive tires until you're ready for them. Until then, find a cheap set of Mustang wheels & tires to push it around in the shop. 17" so they clear even the Wilwood calipers.

Just got my inventory sheet and Parts on Order List (POL) today. Only 15 items back ordered. Serial #1010663. Stewart transportation should drop off on Wednesday or Thursday!
Brakes and shocks coming from Gordon Levy.
Engine and transmission being built.
Quiet pipes on order (maybe another 8 weeks or so I am guessing).

I am fairly excited to get started!

[danmas]

Kelly with Stewart Transportation showed up at 8AM or so this morning. Took about 30 minutes to unload and that involved some paperwork issues (Blue sign on nose wasn't my blue sign. Chassis ID is correct tho!). My daughter got to take the first ride.


And so it begins. Inventory this weekend.
