All of you that are running 245's, do they actully fit inside the fenders? I saw a few cars that were running 245's last weekend, but the tires really didn't fit inside the fenders. In other words, if the suspension travel allowed the top of the fender opening to go lower than the top of the tire, the fender would rub on the tread of the tire. I want the biggest tire that will still fit 'inside' my fender.

I’ve spent a great deal of time searching the forums in order to find out how to setup my suspension. I think I’m finally getting the picture, but I want to make sure I am understanding this correctly. First of all I think that when people say they are using ‘coilovers’, that’s not really what they mean. A suspension setup can only be said to be a true coilover when the body of the shock absorber is threaded and the adjustable spring perch sits on that. I think what people mean when they say they have ‘coilovers’, is an adjustable setup that replaces the lower spring perch with an adjustable one mounted on a threaded collar that is attached to the strut. It is still a strut suspension. I assume that the way you get extra tire clearance when changing to a ‘coilover’ suspension is that a shorter spring is used which allows the lower spring perch to be set higher (without increasing the overall ride height), thus the lower spring perch can be placed above the height of the tire. As far as sectioning the strut, this is only required if you lower the stock ride height more than a specific amount (greater than 2�??). If you section your struts, then you need strut cartridges that are designed for this shorter length. Is my understanding correct?

I went ahead and purchased the wheel adapters from Modern Motorsports. Since it appears that Ross (a member of hybridz) doesn't want to advertise the width of his adapters, I won't post the width of them; but I will let everyone know how they work.

This is the data I've been waiting for. Now I can move forward with starting my LS1 conversion.

Seeing that Ross from Modern Motorsports is a Donating member of Hybridz, I guess I will get his wheel adapters. Hopefully I will get 225/45R17's on 17x7 40mm offset wheels to fit on my unmodified 1973 240Z. 8)

Thanks for the info. BTW - I used the search and couldn't find anything specific to this size wheel and tire combination. Maybe I'm using the search incorrectly, but it's difficult to get it to return good hits. Either I get no matches because I'm too specific, or I get too many that aren't what I'm looking for.

I would like to put a 17x7 set of wheels on my 1973 240Z. I found that technotoytuning.com has a 33 mm thick adapter that will convert me from 4/4.5 to a Honda 4/4 ($180 for a complete set). This should allow me to use a standard 17x7 40 mm offset Honda wheel. Has anyone else used these adapters? Gabriel thanks that I should be able to fit 225/45R17 wheels without any modifications when using their adapters. Has anyone used these size tires on an unmodified 240Z (no fender flares and standard struts)?

Can I ask what wheel adapters you used for your 71 240Z and where you got them? What size rims are you using? 17x7? I'm looking at putting some 17x7 Konig wheels on my 73 240Z. Thanks, Bart

Hi everyone, I just called Thermal Tech, and they seem very friendly and helpful. I'm looking for a header solution for a LS1/T56 conversion into a 1973 240Z. Thermal Tech is going to find out if they have a pair of headers that will work for this application.

Thanks David and Tim for your replies. I started a new topic in regards to the transmission mount issue. -Bart

I'm still fairly new here so I hope I'm doing this correctly. David was nice enough to respond to a post I made in the Speartech Harness topic, but I think it should now move to a new topic. I am planning on putting an LS1/T56 combination into my 1973 240Z. John's transmission mount currently will not work in this year Z. David mentioned that he used the JTR crossmember. Has anyone else tried this? David are you using the DAT-106 part from JTR? The DAT-106 doesn't look a strong as the transmission crossmember that John makes. How long until John has one that will work in early model Z's? Thanks, Bart

Hey everyone, I have a 1973 240Z that I'm planning on converting to a LS1/T56. I will probably use parts from John's Cars to do the conversion. If I get a complete LS1/T56 with everything still connected, will I still need this Speartech Harness Thanks, Bart
