The 7s aren't designed to take a 3-4" drop in the front. By the time you do that, there's no suspension travel left for the front. Since you said slammed, I suspect you've been bitten by the 'tuner' bug, which doesn't correlate to our suspension setups. While 'slammed' may look cool, all it does is fuckup the handling on our cars.

You need to do a lot more studying on suspension setups for our cars. Have you spent any time reading through the race tech section? My guess is you haven't. There's a lot of posts to sort through, but eventually you'll find a few that will help you get the setup you need for drifting. Try and find what some of the other drifters have done for thier cars.

I'm not trying to bag on you, just know that a 3-4" drop doesn't work from what others have tried and it didn't work for them.

Fwiw, Racing Beat used to sell strut tower extensions to increase front end drop and still have the needed suspension travel. The part is NLA

Go with the Respeed stuff. It can't get any more slammed than that! Look in the non-technical section for my post on "new tires for the csp racer" or something like that. I've got pics of the car as it ran for race, and it is very low, and it worked.

Besides, Respeed makes great stuff.

I cut my springs after I orderd the coil overs. Its rough. The re-speeds will cover 3 to four inch drop, but from the month I've have this car. I gotta say the rear diff on the 1st gens is no joke. It doesn't take much to get sideways. A little gas or a clutch kick and off you go... But the moral of the story is that you really dont need to go very low. its really low at stock height. Since i cut em speed bumps and driveways have become a serious problem.

The difference between the 2nd gen diff and the first gen lsd diff is night and day, in drifting.

And the first gen is VERY controllable with little input when sideways.

And it's nice to hear the your not following the rest of the sheep and buying a 240/s13.

Keep bangin, baby

You can cut up to one turn with negligible results, depending on spring type and rating. But I repeat, I cut mine ONLY after ordering the proper kit and I regret it.

You need a setup like the old Racing Beat strut tower extensions. They raise the entire front suspension. New tower tops and RCA's. It would lower a stock car 1.4"....with lowering springs, it will easy be near 3"....with all the travel of a standard lowered car.

UNFORTUNATELY....RB no longer makes em....I have a guy who may try to reproduce....let you know.

for one, i have not been bitten by the tuner bug, if i have been bitten by anything it would be the drift bug, and i dont want to use an fc, because everybody else does, fd's are way too expensive, just in case a wall comes along, and i love the look of old school cars, especially fbs, im not new to the rotary scence as ive had 3 or four fb's in the past, and honestly anything can be slammed and handle if you have the money to do it, trust me on that one, so pretty mush just re-speed makes a coil over kit for the fb? ive seen the rb drop tower kit, i regret not buying the car i saw with that already installed but what can ya do, any one have pics of the re-speed kit on thier ride?

If the strut tower extension interests you, there are ways around that. Find an FB in the junk yard, cut off the strut tower tops and adapt them to your's. There's always a way around problems with some creative thinking. I'm running Eibach's, and almost very suspension mod made for the 1st gens except for the strut tower extensions and coilovers. At this point in time, I really need to raise the front of mine due to the height of the widebody kit. I can't even pull into my driveway without catching it.

If you're going for the lowered look, but still want to maintain suspension travel, you might look into the Mariah Mode 4 front air dam. In the following link is the build on my widebody project. As it sits now, I have about 6" of ground clearence to the bottom of the front lip. The 15" tires and wheels add at least an inch over what the 13" tires and wheels would. Problem is the front air dam is so much farther forward than the stock one, the lip scrapes on dips and my driveway approach.

https://www.rx7club.com/build-threads-293/unvieling-12a-bp-widebody-462184/

As far as cutting out coils in your springs, cut only the dead coils. these are the coils that have no gap between one another. Cutting out coils that have a gap will change your spring rate.

If you really want to slam your 7, look into installing your own strut tower extensions and ReSpeed's coilovers. In all honesty, you don't need to have your 7 slammed in order to make it a great drifter. Most of it comes down to choosing the right suspension components to start with.

My best suggestion before buying parts or modding is talk to Billy at ReSpeed, he'll set you on the right path.

I never measured the drop, but it's pretty low. At race height, I've got about an inch of clearance between the top of the tire and the wheel well. But since its so low, I don't get much body roll (if any) and haven't had any issues with rubbing. Fenders are not rolled.

I shot a lot of video from this past weekend (we had a two day event). The car looks great with those wheels/tires on it, and being as low as it is she feels very stable and controllable, even if you start to slide. I'm very happy with the setup.

I'll post up once the videos are finished and uploaded to Youtube.
