As of today there isn't a stock height option but it will be available very soon.

Speedtech is an impressive unit, but it is $3K more than the Martz unit.

I just want to CALRIFY that the Martz is only 1284.00 less than the Speedtech unit when all the options are included that make them comparible component wise. not 3000.00

Blake I'd love to talk to you because I developed a spreadsheet where I am comparing them and the Speedtech came out to $7967 and the Martz came out to $4965. On the Speedtech this includes the ATS spindle and 13" brake package, universal steering connection kit and $200 crating fee. Oh and I didn't mention the $500 shipping which would make it $8467 because I can pick the Martz unit up at Carlisle, PA in the fall. I wish the difference was only $1300, because I would go with the Speedtech.

feel free to call me i will do up an estimate for you and compare .

if you are adding the AFX spindle you are not making a fair comparison. as the geometry will be FAR better and from the intended use you have stated are not required.

have you seen this

Witch one of all these afthermarket subframes is the lightest??.
becase with all the BS aside when you get one for roadracing then thats the ""only"" thing more intresting then al that other stuff that is supost to make them beter at handling then a stock factory subframe.

There are so manny afther marked suspention goodies availeble that you actualy can ""save"" your money getting a afthermarket subframe and stick it in something els...
I have seen to many stock equipt subframe road racers compeat against purpose build full tube frame cars and win!!..

He overtakes DTM BMW. BMW M1. Kremer 935 K3 1000 hp lemanse winning porshe . Dytona Cobra . most of the cars in his class run with apr 650 to 1000 hp. his set up is FAR from perfect with a 4 speed manual and a 3.08 rear ratio STOCK spindles. he leaves at least 2 sec a lap at the track.
Nevertheless UNLESS you are planning to drive more radical then him then you dont need a afthermarked subframe unless you whant bragging rights...

so what a arms spindles etc do u reccomend

[Roadrage David]

LOL bij the way that car hase ""stock"" lower A arms and SPC upper arms,
and custom euro made coil over shocks with 1000 lbs springs in front!!. and Wilwood brakes

I myself have ATS AFX tall spindels and Speed tech lower A arms and SPC racing upper A arms .Chicane kit(witch we disided not to use) and Afco Elite coil over shocks in the front.. and Brake Man brakes (best Brakes around if you ask me) Lee close ratio stearing box(same as the transam)
Im building a pontiac powerd first gen firebird to compeat against that pontiac powerd transam in the you tube video,s. ...
Point im trying to make is that you can do without a afthermarked subframe unless you whant to go a.al on weight and looks...
It wil NOT give you a advantage over the stock subframe.................have inclosed some pictures of that euro race league

[Roadrage David]

here are some more pictures. This was at the Red Bull ring in Austria last weekend we where at the Hockenheim ring Germany. Video,s where made bij our groop (picture above)

I spent a good deal of time researching the numerous front suspension options available. I looked at installing components on my stock subframe and complete subframes. When all was said and done, adding components saved a little money but required a lot of time to install. I ended up installing the DSE subframe and I have not regretted the choice. I too am not big into track days or auto-X.

Im not sure what resirtch you have done. But I dont call 2200(speed tech bare subframe) usd little money!!. for the averitch worker today!!. and im sure they are""not"" the most exspensife subframe out there!!!!!!!.
so 2200 upto 3000+ usd just for looks and a couple of lbs lighter is NOT the most bang for your buck.

let me see for 2200/3000 usd i can get fibre glass doors, fenders, inner, fenders ,frond bumper, rear bumper, Dek lid , Hood.
and with a little bit of luck blemised persy,s speed glass al round .

now thats saving a lot of weight and getting bang for your $$, if you are building a road racer ore auto cross car.
the rest of the money witch you would spend on a aftermarket subframe,s suspention parts that come with a ""compleat"" subframe, you just spend on practiculy the same suspention parts!!.
that come with that subframe.
and put those on the origenal frame. Now i have a MUTCH lighter car with top notch suspention parts . and because of that a better handling faster car. Boom Done Finished.........
