My 1987 El Camino Conquista

Hello, I'm new to this forum and have recently acquired a 1986 Chevy El Camino at my second home in the Dominican Republic. El Camino's are extremely rare there because no cars less than 5 years old can be imported. I also live in Atlanta, GA and travel back and forth often, so I typically bring parts and supplies with me from the US when traveling there. I just brought in four 17x8 Vision (Hurst) Dazzlers for the car with 0mm offset into the D.R. recently. On my next trip, I'm bringing the tires.

I want to raise the rear up 1.5 or 2" due to the numerous speed bumps and crazy road terrain in the D.R. (height depending on final wheel size) and brought rear lifting blocks and rear shock extenders only if needed.

Now that you have the backstory... I'm wondering if any of you could assist with a few questions. I want to put 275 tires on the back but am concerned about fender rubbing and/or interior component rubbing. I don't want to make any fender mods so I'm wondering if 275/40/ r17 is a good idea for the rear.

Here is the proposed plan... with your expertise I was wondering if you could give me your thoughts?

FRONT:

Original:

• Wheel: 14x6.5
• Tire: 205/20 r17
• Offset: -3mm

Proposed:

• Wheel: 17x8
• Tire: 235/45 r17
• Offset: 0mm

REAR:

Original:

• Wheel: 14x6.5
• Tire: 205/20 r17
• Offset: -3mm

Proposed:

• Wheel: 17x8
• Tire: 275/40 r17
• Offset: 0mm
• 1.5" rear lift blocks (no rear shock extenders) -or- 2.0" lift blocks (with rear shock extenders)
• no rear spacers (preferred)
• no fender mods (preferred)

QUESTIONS:

1) Will the above configurations work without the need for rear fender mods or rear spacers?
2) If not... what is the widest tire recommended to avoid any rear fender mods or rear spacers?


I am also posting this question here on this discussion thread that I opened... https://www.elcaminocentral.com/threads/any-rubbing-with-275s-on-rear.246586/ but I was hoping you saw it so I am also posting it to your personal page. Any help would be appreciated!
