Turner Motorsport suspension question.

[LokeyVW]

Has anyone tried the E30 Turner Mortorsport J-Stock Suspension System?

I am trying to put together a very competitive suspension that is still somewhat streetable. I have searched around a bit here on the forums and have not come across this setup yet. I now its pricy at 2k but sway bars are around 440 springs 300+ camber plates 250+ stuts 400+ and the Turner setup comes with upper strut bearings rear shock mounts and a reinforcement kit.

Is it worth it to just pick up this kit and call it a day or is it just over priced since its all bundled together and has the Turner Motorsport name on it?

Thanks for any help, I would rather get the opinion of people who have been around the E30's for a while before I drop some serious cash on suspension.

If it matters I already ordered tires that are 225/45R15 Ventus RS-3's and will be picking up new lightweight wheels once I decide between RPF1, Kosei K1 and the TR C1's

Thanks!

The J-Stock springs are 680/1026, and you need to match them with the Turner custom valved Bilsteins. I've never heard of anybody trying to run these on the street. That's STIFF!

[LokeyVW]

Yeah the kit on the Turner site comes with the revalved shocks. I didn't realize the springs were so stiff but if the shocks are valved to match it shouldnt be too terrible haha

Just wondering if anyone has actually tired this sillyness on a car that sees street duty.

I might just end up buying things individually and going with the HR springs and bilstein struts.

Even the H&R Race are nowhere near as stiff as the Turner J-Stocks.

I'd recommend going with a Ground Control coil-over set up. You can customize the spring rates, and have adjustable height as well. They sell custom valved Koni's also.

I have looked into GC and I am not opposed to that route, just thinking it would be nice to get something like the turner kit that is designed to all work together to provide the best handling possible.

I bought the springs and had my bilstein sports revalved to match. I love the handling. It is extremely stiff for the street though.

Sounds like you have your mind made up then.

You wanna be competitive? AST suspension. THEN you call it a day, lol. on a real note, I start slow and upgrade as you go. I don't know what you have done to your car yet, but if you are actually being serious about the "competitive" shit, then you have preventative maintenance to do. Replace the bushings. ALL OF THEM. Then reinforce your subframes. Reinforce your trailing arms. Check your wheel bearings. And what are your goals? Am I wasting my typing breath on an "AutoX/DD" or is this thing actually being tracked?

go with the turner kit. replace bushings. let everyone know how it works for you.
nothing wrong with being different

I am seriously leaning towards the Turner setup that is true but I wanted to see if anyone has run them on the street.

I will be calling them Monday to verify the suspension will work on the 84-85 318I since it has different strut housings and to request it without the Turner Motorsport camber plates since I want the extra travel GC plates provides.

Just keep in mind that suspension that stiff on many roads, and even some racetracks, can result in the car skipping across uneven pavement and losing contact with the ground/ decreasing your handling performance. You sound like you know what you are doing but I just have to put that out there just in case

My past encounters with upgraded suspension is from my MK2 VW's and on those I liked the Neuspeed Race Springs with Tokico 5 way adjustable dampers or the Koni fuly adjustable coils. What I am finding out about E30's is you typically run either stiff springs and no sways or soft springs and big sways. This is quite a bit different than VW's where a stiff spring went well with a large rear anti roll bar.


I actually just drove the car home and it feels like a boat, I am guessing all the bushings are shot and the stuts are blown so the car will be getting a complete (every bushing possible) overhaul along with upgraded stuts springs sways and reinforcement kit. But before thats going to get to happen I need to get the basics out of the way, and yes I have a Bentley manual in the mail right now...

I've driven a race car with the J Stock springs and I can only imagine how bad that would be on the street. J Stock springs are amost exactly twice the spring rates of H&R race. My Spec E30 (with H&R race springs) is almost punishing on the street.

Thanks for the heads up! That is the kind of first hand info I was hoping to get from this thread. I will be ordering new brakes bushings and maint stuff on Monday!

[LokeyVW]

Well order placed, based on my research and the opinons of both jlevie and someone local to me who have run the J Sport setup I decided it is probably too much for my needs. I went with the HR Race springs with Bilstien Sprot Shock in the NASA Pro Spec E30 kit that comes with all the reinforcment bits along with sway bars and new rear upper bushings. Also picked up some rear trailing arm bushings and KMAC front camber plates, and wheel studs to make life easier. But most importantly I have a Bentley Manual on the way

I also ordered a 5 piece poly bushing kit for the front control arms and a slew of basic maint parts. Tires are on order (225/45R15 Ventus RS-3's) and wheels (TR C1's in 15x8) will be soon!

I dont think I am missing anything for a full suspension overhaul? I have heard good things about the rear strut brace but that will come in a few weeks/months at the same time as I have a cage welded in.

My hope is to have an aggressive street driven car that is just as comfortable on the track and twisty back roads.
